RF transceiver chip for 868/915 MHz SRD band

28 February 2001 Telecoms, Datacoms, Wireless, IoT

Chipcon Components is continuing the success of its CC400 RF transceiver (for use from 300-500 MHz) by introducing the CC900 RF transceiver for the 800-1000 MHz band. The CC900 is a one-chip FSK radio transmitter and receiver intended to be used in the license-free 868 MHz and the US 915 MHz, SRD band. It can be used in all the different frequency bands around 868 MHz and fulfils the requirements for 25 kHz channel spacing.

It has the capability of FHSS. A frequency resolution down to 250 Hz makes crystal temperature compensation possible with no external TCXO. The range is up to 500 m and data rates up to 9,6 kbps. Output power is programmable from -20 to 4 dBm and the receiver sensitivity is -110 dBm for BER 10e-3 at 1,2 kbps. The receiver current consumption is 23 mA at 3 V supply voltage and in power down mode it consumes only 0,2 µA.

Chipcon Components also provide the SmartRF Studio software for the CC900, where all the necessary configuration data is generated in a format that is easily included in any microcontroller code. A development kit is available and a demonstration kit for the CC900 RF transceiver will be available soon.
