A low-cost low-power area-efficient receiver front-end prototype for X-band applications is presented. The front-end primarily consists of 3 blocks: a single ended input differential-output Low noise amplifier (LNA), a double balanced down-converter, and Inter-frequency (IF) buffers providing single-ended output. Including are also Low dropout regulators (LDO) and Electrostatic discharge (ESD) protection circuits coinciding with the forgoing blocks. Local oscillator (LO) frequency is chosen such that output signal locates in L/S-band for extending subsequent applications. Experimentally exhibiting a conversion gain of around 44dB with 7.5-dB Single-sideband (SSB) Noise figure (NF), the front-end totally draws 24mA from an external 3.3-V supply. Fabricated in a 65-nm CMOS technology, this compact receiver occupies an area of only 0.22mm(2).
