Highly linear 20 GHz-Micromixer in SiGe bipolar technology
An active mixer operating at 20 GHz based
on the Gilbert Micromixer topology was designed and
fabricated in SiGe technology. High performances are
measured and especially an excellent linearity for moderate
current consumption is demonstrated. The circuit shows an
Output IP3 of +12 dBm and a conversion gain Gc of +7.7 dB
for an optimum LO power of only -2 dBm. The bias current
in the entire circuit is only 25 mA for a chip size of 1.8 x 2
mm²
