2,4 GHz RF transceiver

28 August 2002 Telecoms, Datacoms, Wireless, IoT

Micro Linear's ML2712 combined with the company's ML2713 comprises a FSK (frequency shift keying) 2,4 GHz radio chipset.

The ML2712 contains the RF and PLL circuits for a half duplex radio transceiver solution for IEEE802.11 and other wireless communication protocols using the 2,4 GHz ISM band. The device is controlled using a three-wire programming interface and three control lines. The transmit circuits feature an RF down-converter for a transmit frequency translation loop and a Wideband Phase Detector for a directly-modulated VCO transmitter. An RF down-converter mixer is provided for receive. All frequency generation circuits are integrated for the RF conversion, the 1 LO VCO and PLL plus a 2 LO VCO and PLL for use in dual conversion radios.

In addition the ML2712 contains an 8 bit D/A & Comparator that may be used together as a tracking A/D for Received Signal Strength Indication measurement (RSSI).
