AT86RF535A Block Diagram TX Power Control RX Gain Control Synthesizer Driver Config Register 5108B- Wi Max- 2/06 Description Atmel’s AT86RF535A is a fully integrated, low cost RF 3.5GHz Low-IF conversion transceiver for Wi Max applications. It bines excellent RF performance with low current consumption at the smallest die size. The AT86RF535A chip is fabricated on the advanced AT46000 Si Ge Bi CMOS process. The transceiver bines 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 ponents is limited to only a few devices. Quick Reference Data Table 1.
