Product Perspective This Radio module version is constrained to 406.1125-419.9875MHz, 0dBm to 24dBm, GFSK modulation and 30% maximum duty cycle. The Radio modules is to achieve full interchangeability between product model lines, maintaining mechanical and software interfaces as well as physical dimensions is a general objective. 2.1.1. User Interfaces All interface between this module and the User will be software controlled by the product hosting this module. Features such as Frequency, Power and Modulation are all controlled by the Host device. 2.1.2. Hardware Interfaces This product will have two hardware interfaces, these are the RF Port and a 50 pin I/O connector carrying the microcontroller interface and power lines. The 50 pin interface will have a 4 wire serial interface, consisting of Clock in, Data out, Data in and Load. Power: Vbat, 3V3 synth and E2Prom 3-5V I2C interface to store personality. Power control interface consisting of 2 wire power set and one wire PA amp on Data I/O 1 wire out 1 wire in Chip enable 1 wire. 2.1.3. Software Interfaces This module will require the configuration of 15 Data Registers by the operating firmware that set the operating parameters.

User Characteristics Operators: Require no knowledge of this part, all configuration is taken care of in the engineered product. Technicians: The programming of this device is effected by the connected encoder, the encoder can choose to program the device according to it’s own programming or it can take the configuration table from the eeprom on the radio module. Therefore the radio module may be independently programmed with the register table, or programmed by the controller housing it. 2.4. Constraints This subsection describes any items that limit the developer’s options. These include: FCC Part 90 rules ETSI EN300-220v2.1.1 (or later) EN301-489 DOD Chapter 5.3.2 rules Exi limitations imposed on individual components, e.g. maximum capacitance or inductance. Interconnectivity compatibility with URM physical interface. Interconnectivity compatibility with URM programming interface. Physical size for interchangeability with Unity products and current Cattron Toggle and Paddle. RF Connector type MMCX Limitation of Human body exposure. 2.5. Assumptions and Dependencies It is assumed that this device may need to be revised if any of the constraint’s change. It is also assumed that the requirements of narrow banding will ultimately force the use of 3GFSK or 4GFSK and a consequential upgrade in decoder receiver technology. Any actual changes will require further FCC submissions for approvals.

Power Requirements There are three power sources required for operation VBat : 5V-16Vdc @500mA The module power consumption will vary with output power. Maximum requirements for Vbat used to supply the PA will be 500mA at 27dB. during transmit. Maximum duty cycle will be <30%, typically <10% with a consequential overall reduction in average power. 3V3: 3V+- 10% @ 100mA 3V3 EEPROM : 3V+-10% @ 100mA 3.4.4. Software Requirements 3.4.4.1. Overall Timing TX Mode The control of the ENA, PA-ON, G8 and G16 lines need to be sequenced to comply with the following general sequence. Before progressing to the next state it must be verified by read back that the prior stage is complete, i.e. Regulator ready, VCO ready, etc, otherwise use the following timings. Note that due to digital filtering latency it is necessary to maintain RF ON and DATA CLK for a number of clock cycles after completion of data loading, typically this latency will not exceed 5 clock cycles, failure to do this may result in early termination of tx data.

RF Exposure Requirements Compliance with SAR RF Exposure restrictions require the integrated radio to maintain specific characteristics, these are The antenna used must have a maximum gain of +2dBi. The Antenna must also maintain a distance of greater than 3 inches from the body when worn by the equipment user. (Ensured by the body harness used.) The Mean radiated power must remain below 320mW, (equivalent to 60% duty cycle, 3dBd gain antenna and 250mW output power setting); Given that the maximum power is 250mW, the antenna is +2dBi and the maximum duty cycle is actually 30%, this is a very safe factor of safety. 3.5.

Maintenance of, Manufacturing, Re-design, Approvals and Testing and continuous improvement shall fall within the requirements of the quality control system. 3.5.2.
