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 localoscillator
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.
