AT86RF535A
Description
Atmel’s AT86RF535A is a fully integrated, low cost RF 3.5GHz Low-IF conversion transceiver for WiMax applications. It
combines excellent RF performance with low current consumption at the smallest die size. The AT86RF535A chip is fabri-
cated on the advanced AT46000 SiGe BiCMOS process. The transceiver combines LNA, PA driver, RX/TX mixer, RX/TX
filters, VCO, Synthesizer, RX Gain control, and TX Power control, all fully digital controlled. The number of external compo-
nents is limited to only a few devices.
