APPLICATION NOTE 806

RF ICs for 3.5GHz WLL Transceivers
Abstract: This article provides a block diagram of the RF ICs available at 3.5GHz for wireless local loop (WLL) transceivers. The MAX2645 Silicon Germanium low-noise amplifier (LNA) provides a 25dB gain step from digital logic. The MAX2684 will upconvert from 1GHz and downconvert to a 1GHz IF. The MAX2620 is a voltagecontrolled oscillator (VCO) with two buffered outputs. VCO buffer amplifiers, MAX2472 and MAX2473 maintain high isolation and keep harmonics -25dBc. Additional Information:
