1 / 18 page GENERAL DESCRIPTION The ML2713 combined with the ML2712 forms an FSK (Frequency Shift Keying) 2.4 GHz radio chipset for systems based on IEEE802.11 and other wireless communication protocols using the 2.4HGz ISM band. The ML2713 is the complete IF section of Micro Linear’s 2.4GHz frequency hopping, half duplex radio transceiver chipset. The chip’s down conversion super-heterodyne receiver circuit contains an image reject down-convert mixer, a limiter, a discriminator, a receive data filter and a tracking A/D converter. The chips transmit circuit contain a 6 bit D/A converter to digitally modulate the IF, an anti alias filter and an image reject up-convert mixer. FEATURES n Highly integrated IF transceiver n Data rates up to 4Mbps n Integrated discriminator and filter alignment circuits n High signal to noise ratio at the discriminator output n Received signal strength indicator (RSSI) n D/A Converter for digitally generated IF n Low sleep mode current - typically less than 1mA n 3.0V to 5.5V operation n Fast 10msec switch time between transmit and receive modes n 48 Pin TQFP, 7mm body ML2731 Bias Controller Transmit Power Amplifier R.
