1.3 Operation

The MRF24J40MC module is based on the Microchip

Technology MRF24J40 2.4 GHz IEEE 802.15.4 RF

Transceiver IC. Serial communication and

configuration are documented in the “MRF24J40 Data

Sheet” (DS39776).

This section emphasizes operational settings that are

unique to the MRF24J40MC module design that must

be followed for proper operation.

1.3.1 PA/LNA CONTROL

Operation of the PA U3 and LNA U2 is controlled by the

MRF24J40 internal RF state machine through RF

switches, U1 and U4, and the GPIO1 and GPIO2 pins on

the MRF24J40. Figure 1-5 shows the PA/LNA block

diagram. Figure 2-2 is the schematic diagram for the

module.

The internal RF state machine is configured for the PA/

LNA mode by setting TESTMODE (0x22<2:0>) = 111.

Pins GPIO1 and GPIO2 control the RF switches, PA

and LNA automatically when the MRF24J40 receives

and transmits data.

Voltage regulator U5 supplies a regulated 2.2V to the

PA. This provides a stable voltage to the PA over the VIN

voltage range of the module. U5 is enabled or shutdown

from GPIO3. Ensure that the GPIO3 direction has been

set to output (TRISGP3 (0x34<3>) = 1). Setting a logic

high (GPIO3 (0x33<3>) = 1) enables the voltage

regulator and supplies voltage to the PA. Setting a logic

low (GPIO3 (0x33<3>) = 0) will shutdown the voltage

regulator, disabling the PA, and provides the lowest

shutdown current.

FIGURE 1-5: PA/LNA BLOCK DIAGRAM

Note: A complete explanation of the operation of

the PA/LNA control is documented in the

“MRF24J40 Data Sheet” (DS39776),

Section 4.2 “External PA/LNA Control”.

1.3.2 ENERGY DETECTION (ED)

Before performing an energy detection (see Section

3.6.1 “RSSI Firmware Request (RSSI Mode 1)” in the

“MRF24J40 Data Sheet” (DS39776)), perform the

following steps:

1. Configure the internal RF state machine to normal

operation (TESTMODE (0x22F<2:0>) = 000).

2. Configure GPIO2 and GPIO1 direction for

output (TRISGP2 (0x34<2>) = 1 and TRISGP1

(0x34<1>) = 1).

3. Set GPIO2 (0x33<2>) = 1 and GPIO1

(0x32<1>) = 0. This enables the LNA and

disables the PA.

4. Perform the energy detection following the steps

in Section 3.6.1 “RSSI Firmware Request (RSSI

Mode 1)” in the “MRF24J40 Data Sheet”

(DS39776).

1.3.3 SLEEP

To get the lowest power consumption from the

MRF24J40MC module during Sleep, it is necessary to

disable the PA, PA voltage regulator and LNA. To do

this, perform the following steps:

1. Configure the internal RF state machine to normal

operation (TESTMODE (0x22F<2:0>) = 000).

2. Configure the GPIO3, GPIO2 and GPIO1

direction for output (TRISGP3 (0x34<3>) = 1,

TRISGP2 (0x34<2>) = 1 and TRISGP1

(0x34<1>) = 1).

3. Set GPIO2 (0x33<2>) = 0 and GPIO1 (0x32<1>)

= 0. This disables the LNA and the PA.

4. Set GPIO3 (0x33<3>) = 0. This shuts down the

voltage regulator U5 that supplies 2.2 volts to

the PA.

5. Put the MRF24J40 to Sleep following the steps

in the “MRF24J40 Data Sheet” (DS39776).

When waking the module, re-enable the PA/LNA mode.

Note: The LNA will amplify the received signal.

The RSSI value will include the receive

signal strength plus the LNA amplification.

NOTES:

MRF24J40MC

2.0 CIRCUIT DESCRIPTION

The MRF24J40MC is a 2.4 GHz IEEE Std. 802.15.4™

compliant surface mount module with integrated crystal,

internal voltage regulator, matching circuitry, power

amplifier, low noise amplifier with 50Ω external antenna

connector.

The MRF24J40MC module interfaces to many popular

Microchip PIC microcontrollers through a 4-wire SPI

Interface, interrupt, wake, reset, power and ground. An

example application schematic is illustrated in

Figure 2-1.

Serial communications and register definitions for the

MRF24J40MC module are documented in the

“MRF24J40 IEEE 802.15.4™ 2.4 GHz RF Transceiver

Data Sheet” (DS39776). Refer to the “MRF24J40 Data

Sheet” for specific serial interface protocol and register

definitions. Also, see Section 1.3, Operation for specific

module.

2.1 External Antenna

The MRF24J40MC module has a 50Ω ultra miniature

coaxial (U.FL) connector to connect to an external 2.4

GHz antenna. The choice of antenna is limited to the

antenna types the module has been tested with. Refer

to the respective country in Section 3.0, Regulatory

Approval for a list of tested and approved antenna

types that may be used with the MRF24J40MC

module.

2.2 Module Schematic

A schematic diagram of the module is illustrated in

Figure 2-2 and the Bill of Materials (BOM) is shown in

Table 2-1.

The MRF24J40MC module is based on the Microchip

Technology MRF24J40 IEEE 802.15.4™ 2.4 GHz RF

Transceiver IC (U6). The Serial I/O (SCK, SDI, SDO

and CS), RESET, WAKE and INT pins are brought out

to the module pins. The SDO signal is tri-state buffered

by U7 to solve a silicon errata, where the SDO signal

does not release to a high-impedance state, after the

CS pin returns to its inactive state.

Crystal, X1, is a 20 MHz crystal with a frequency

tolerance of ±10 ppm @ 25°C to meet the IEEE Std.

802.15.4 symbol rate tolerance of ±40 ppm.

A balun is formed by components: L11, L12, L13, C25,

C27 and C31. L12 is also a pull-up for the RFP and

RFN pins on the MRF24J40. C25 also acts as a DC

block capacitor. RF switches, U1 and U2, switch

between the power amplifier, U3, when transmitting

and low noise amplifier, U2, when receiving. A

band-pass filter FL1 is placed after the PA U3 to reduce

harmonics. The remaining passive components

provide bias and decoupling.

3.0 REGULATORY APPROVAL

The MRF24J40MC module has received regulatory

approvals for modular devices in the United States and

Canada. Modular approval allows the end user to place

the MRF24J40MC module inside a finished product

and not require regulatory testing for an intentional

radiator (RF transmitter), provided no changes or

modifications are made to the module circuitry.

Changes or modifications could void the user’s

authority to operate the equipment. The end user must

comply with all of the instructions provided by the

Grantee, which indicate installation and/or operating

conditions necessary for compliance.

The MRF24J40MC module has been tested and

conforms to EN 300 328 V1.7.1 (2006-10), European

Standards. The module tests can be applied toward

final product certification and Declaration of Conformity

(DoC). Additional testing may be required depending

on the end application.

The integrator is still be responsible for testing the end

product for any additional compliance requirements

required with this module installed (digital device

emission, PC peripheral requirements, etc.) in the

specific country that the end device will be marketed.

Annex F of the IEEE Std. 802.15.4 document has a good

summary of regulatory requirements in various countries

concerning IEEE Std. 802.15.4 devices. The standard

can be downloaded from the IEEE Standards web page:

http://standards.ieee.org/getieee802/802.15.html.

For more information on details on regulatory

compliance, refer to the specific country radio

regulations in the following sections.

3.1 United States

The MRF24J40MC has received Federal

Communications Commission (FCC) CFR47

Telecommunications, Part 15 Subpart C “Intentional

Radiators” 15.247 and modular approval in accordance

with FCC Public Notice DA 00-1407 Released: June

26, 2000, Part 15 Unlicensed Modular Transmitter

Approval. The MRF24J40MC module can be

integrated into a finished product without obtaining

subsequent and separate FCC certification.

The MRF24J40MC module has been labeled with its

own FCC ID number, and if the FCC ID is not visible

when the module is installed inside another device,

then the outside of the finished product into which the

module is installed must also display a label referring to

the enclosed module. This exterior label can use

wording as following:

The user’s manual should include the following

statement:

Contains Transmitter Module FCC ID:

OA3MRF24J40MC

(1) this device may not cause harmful interference,

and (2) this device must accept any interference

received, including interference that may cause

undesired operation.

This equipment has been tested and found to comply

with the limits for a Class B digital device, pursuant to

part 15 of the FCC Rules. These limits are designed to

provide reasonable protection against harmful

interference in a residential installation. This

equipment generates, uses and can radiate radio

frequency energy, and if not installed and used in

accordance with the instructions, may cause harmful

interference to radio communications. However, there

is no guarantee that interference will not occur in a

particular installation. If this equipment does cause

harmful interference to radio or television reception,

which can be determined by turning the equipment

OFF and ON, the user is encouraged to try to correct

the interference by one or more of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment

and receiver.

• Connect the equipment into an outlet on a

circuit different from that to which the receiver is

connected.

• Consult the dealer or an experienced radio/TV

technician for help.

3.1.3 RF EXPOSURE

All transmitters regulated by FCC must comply with RF

exposure requirements. OET Bulletin 65 “Evaluating

Compliance with FCC Guidelines for Human Exposure

to Radio Frequency Electromagnetic Fields” provides

assistance in determining whether proposed or existing

transmitting facilities, operations or devices comply

with limits for human exposure to RF fields adopted by

the Federal Communications Commission (FCC). The

bulletin offers guidelines and suggestions for

evaluating compliance.

If appropriate, compliance with exposure guidelines for

mobile and unlicensed devices can be accomplished

by the use of warning labels and by providing users

with information concerning minimum separation

distances from transmitting structures and proper

installation of antennas.

The following statement must be included as a

CAUTION statement in manuals and OEM products to

alert users of FCC RF Exposure compliance:

If the MRF24J40MC module is used in a portable

application (antenna is less than 20 cm from persons

during operation), the integrator is responsible for

performing Specific Absorption Rate (SAR) testing in

accordance with FCC rules 2.1091.
