Transmitter Characteristics
The AT86RF535A is a fully integrated, low-cost Low-IF conversion transceiver for WiMax appli-
cations and is based on the IEEE 802.16-2004 standard. This product will provide transmit,
receive, and frequency synthesis functions OFDM modulation schemes, as defined in the above
specifications. It combines excellent RF performance at low current consumption. The trans-
ceiver 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 components is limited to
only a few devices. The AT86RF535A consists of a frequency-agile RF transceiver intended for
use in 3.5-GHz licensed bands at data rates up to 26Mbps. Configuration and control registers
and a bi-directional data communications interface to existing baseband devices from different
vendors will be included. The AT86RF535A addresses the requirements of base station (BS) as
well as subscriber station (SS) equipment. The device will operate down to 3.0V. The
AT86RF535A is fabricated in Atmel’s AT46000 advanced SiGe BiCMOS process technology
and is assembled in a 8mm x 8mm 56-lead QFN package.
The differential low noise amplifier (DLNA) makes use of a differential bipolar stage with resistive
emitter linearization. For digital gain control operation, the DLNA supports the four gain modes
