Summary:
A V-band compact monolithic up-converter and down-converter were designed and tested. Each frequency converter was highly integrated with RF and LO amplifiers into a single compact chip. To avoid undesirable resonance, the chip width was limited to 0.9 mm. The up-converter has a balanced configuration to suppress undesired LO leakage. Using the uniplanar concept, the chip size of each frequency converter was greatly reduced to only 2.6 mm². Measured performance of the up-converter includes conversion gain of-10.6 dB

3.3 dB for a bandwidth of 10 GHz, and LO leakage is more than 10 dB below LO input. The down-converter shows a conversion gain of -0.4 dB
