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.

44 PIN TQFP

¹Modulation 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

²Measured at 1200 bps and frequency deviation ± 10kHz (XCO modulation). The baudrate is equal to the bit rate.

³Tentative specification.

Parameter temperature dependency will be specified after full characterisation.
