Single-chip FSK/ASK RF transceiver for narrowband and multichannel applications

19 November 2003 Electronics Technology

Chipcon is a leading provider of standardised and customised RF-ICs and is represented locally by Components & System Design. Less than two months after Chipcon released the award winning CC1010, said to be the industry's only true RF system-on-a-chip, Chipcon set another high standard within the low-power, low-cost RF-IC market, with the CC1020.

This is a single-chip CMOS RF transceiver with performance at a level that, according to Chipcon, no other company to date, has achieved for single-chip solutions.

The CC1020 is designed for FSK and ASK systems operating in the 424 to 470 MHz and 848 to 940 MHz frequency bands. Typical bands are 426, 429, 433, 868 and 902-928 MHz. Key features of the CC1020 include:

* Receiver sensitivity up to -119 dBm.

* Programmable data rate up to 153,6 Kbps.

* Selectivity (25 kHz systems): 30 dB adjacent channel rejection and 40 dB alternate channel rejection.

* Adjacent Channel Power (25 kHz systems): -45 dBc.

* Power supply: 2,3-3,6 V.

* Narrowband digital RSSI function.

* Intelligent wake-up circuitry for power management.

* Full on-chip VCO.
