Abstract :
In this paper, we present the design and implementation of the RF front-end for the WiMAX (802.16e) and WLAN (802.11n) standards. The front-end covers the frequency ranges of operation for licensed and unlicensed bands of WiMAX and WLAN, which include 2.3 GHz - 2.9 GHz, 3.3 GHz - 3.7 GHz and 4.9 GHz - 5.9 GHz. The gain of the front-end is between 30 - 32 dB for all the bands while achieving noise figures of 2.5 dB, 3.5 dB and 5.9 dB at the center frequencies of the lower, middle and upper bands respectively. The total front-end operates at the bias current of 26.25 mA and consumes 48 mW of power. The components include in the front-end are low noise amplifier, active balun or single to differential converter and mixer. The design of the front-end is performed in 1.8 V IBM CMOS 0.18mum process
