Preliminary
Description
Atmel’s AT86RF535B is a fully integrated, low cost RF 3.5GHz Low-IF/Zero-IF con-
version transceiver for WiMAX applications. It combines excellent RF performance,
small size, and low current consumption. The AT86RF535 chip is fabricated on the
advanced SiGe BiCMOS process AT46000. The transceiver combines LNA, PA
driver, RX/TX mixer, RX/TX filters, VCO, Synthesizer, RX Gain control, and TX Power
control, all fully digitally controlled. Only a minimum number of external components
are required.
