Abstract
In this paper, we present MIMIC(Millimeter-wave Monolithic Integrated Circuit) up-mixer with low conversion loss and low LO power for the V-band transmitter applications. The up-mixer was successfully integrated by using 0.1 ㎛ GaAs pseudomorphic HEMTs(PHEMTs) and coplanar waveguide (CPW) structures. The circuit is designed to operate at RF frequencies of 60.4 GHz, IF frequencies of 2.4 GHz, and LO frequencies of 58 GHz. The fabricated MIMIC up-mixer size is 2.3 mmxl.6 mm. The measured results show that the low conversion loss of 1.25 dB when input signal is -10.25 dBm at LO power of 5.4 dBm. The LO to RF isolation is 13.2 dB at 58 GHz. The fabricated V-band up-mixer represents lower LO input power and conversion loss characteristics than previous reported millimeter-wave up-mixers.
