QFM-TRX1-24G

2.4GHZ TRANSCEIVER MODULE QFM-TRX1-24G Features • Complete RF Transceiver • Onboard Data Encryption • Automatic collision avoidance • ‘Wake on Radio’ feature • Low current consumption • Wide Operating voltage 1.8 – 3.6 Volts • Operating Frequency: 2.4 – 2.483 GHz • Programmable Output Power and High Sensitivity • Range up to 50 metres at +1dBm • Data rate 1.2 – 500 kbps Applications • Consumer Electronics • Wireless controllers • Wireless Audio • Wireless PC peripherals • Building / Home Automation Description The Quasar UK ‘TRX1’ hybrid transceiver module provides a complete RF subsystem which can be used to transmit and receive data at up to 500Kbps from any standard CMOS/TTL source. Extensive hardware support is provided for packet handling, data buffering, burst transmissions and link quality indication. Automatic collision avoidance is also provided with the clear channel assessment features. The modules are ideal for battery powered applications, current consumption is reduced with the burst transmissions and wake on radio features. The data stream can be automatically Manchester encoded and decoded ensuring high reliability and low error rates. The modules frequency, output power and sensitivity are all programmable through an efficient SPI interface.
