A direct conversion WiMAX RF receiver front-end in GaAs 0.5µm ED-mode pHEMT technology

This paper presents a direct conversion RF receiver front-end supporting the WiMAX (802.16e) standard. The front-end is implemented in 0.5 um GaAs ED-Mode pHEMT technology and designed using the ADS 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 13 dB.
