FCC Statement
FCC Part 15.19
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
NOTE:
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.
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
No special accessory is required to enable the equipment to comply with the emission
limits.

1. Introduction
1.1
General description
The KWR112401/01B remote control is based on the GP500C communication
controller chip.
The chip is fully compliant with the IEEE 802.15.4 standard, providing robust spread
spectrum data communication with a highly secure encrypted data flow. It features a
radio transceiver, integrated real-time MAC, an event scheduler, a security
processor, advanced power management features, and a high-speed SPI interface
to a microcontroller.
A RF4CE remote control unit can be build with a GP500C plus a microprocessor,
supporting the keyboard scanner and the IR interface for compatibility with legacy
targets.
1.2 Frequency synthesis and modulation
The GP500C is using a PLL circuit with a VCO on 2 times the transmit frequency.
The VCO is directly modulated by the digital signal processor (DSP). The modulation
is fully compatible with the offset quadrature phase-shift keying (O-QPSK) as
required by the IEEE802.15.4 standard.
1.3 RF interface
The GP500C does have two RF outputs: RF1 and RF2. Both RF ports are
bidirectional and will be used for both transmit (TX) and receive (RX) mode. The
signal configuration of the RF ports is differential. The differential configuration is
maintained up to the antenna, so the remote control is using a differential matching
and low pass filters and also differential antennas.
Biasing of the power amplifier (PA) and diversity switch is supplied by the VCM pin of
the GP500C and is injected into the low pass filters
1.4
Antenna diversity
The GP500C is supporting antenna diversity over two antennas. For every received
packet the digital signal processor in the GP500C will select the antenna with the
best signal. The decision is made at the very beginning of the packet. Normally the
transmitter will use the antenna that was used to receive the last packet. The result
of the antenna diversity mechanism is that either RF port 1 or RF port 2 can be used
for transmit; there is only one antenna transmitting at the time.
