APPLICATION NOTE 806
RF ICs for 3.5GHz WLL Transceivers
Nov 14, 2001
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 voltage-controlled oscillator (VCO) with two buffered outputs. VCO buffer amplifiers,
MAX2472 and MAX2473 maintain high isolation and keep harmonics -25dBc.
