A Direct Conversion WiMAX RF Receiver Front-End in CMOS Technology

Abstract

This paper presents a direct conversion RF receiver front-end supporting the WiMAX standard. The front-end is implemented in 0.18um CMOS technology and designed using the ARCHER software. It shows how the design flow can be accelerated starting from the standard specifications and going down to schematics. All this is accompanied by test benches to extract the relevant metrics. This front-end provides a total gain of 31dB, a noise figure of 3.3dB, an IIP2 of 49.5dBm, and an IIP3 of -13.8dBm.
