Abstract:
The design of a subharmonic downconverter for 94-GHz imaging arrays in SiGe:C technology is presented. A three-stage differential low-noise amplifier (LNA) with lumped matching networks is used together with a subharmonic mixer driven by a single-pole local-oscillator poly-phase network to form the front-end. The LNA yields 15 dB gain at 94 GHz, while the mixer provides 5 dB conversion gain over a 10 GHz IF bandwidth. The integrated downconverter provides 20 dB conversion gain at 94 GHz with an input 1-dB compression point of −31 dBm and has a current consumption of 45 mA at a 3.3 V supply voltage. The total required die area of the complete downconverter (excluding pad frame) is 0.1 mm, thus making it particularly suitable as a front-end in multi-channel receiver systems.
