GJRF400
SINGLE CHIP RF TRANSCEIVER
The GJRF400 is a single chip integrated circuit for radio-
based frequency hopping spread spectrum
communication. (FHSS) The circuit is easily applied and
RF-knowledge requirements are minimal. The circuit can
be utilised in homes, health care and industry in various
ways and can be applied in alarms, garage ports, remote
controls, etc., and in more complex systems for control,
monitoring and low data-rate communication between
computers. A typical system consists of a microprocessor
and a radio circuit plus some external components.

1_{Modulation is applied to the VCO and is based on a transmission code where the baudrate is twice the bitrate (e.g. Manchester code ).}
9600bps = 19200 baud
2_{Measured at 1200 bps and frequency deviation ± 10kHz (XCO modulation). The baudrate is equal to the bit rate.}
