چکیده

A planar millimeter-wave third-harmonic mixer with low conversion loss is proposed. The mixing circuit consists of a substrate-integrated waveguide (SIW) balun, a pair of diodes, a diplexer and microstrip matching circuit. The mixer is ideal for use as down-converter and up-converter. For a fixed intermediate frequency (IF) of 2 GHz, the mixer has an up-conversion loss of 14.5-15.6 dB and a down-conversion loss of 14-15.6 dB over the radio frequency (RF) band of 38-47 GHz. For a fixed local oscillation (LO) frequency of 13 GHz, the mixer has a conversion loss of 10-15.8 dB over the IF frequency band of DC-6.4 GHz. The proposed mixer offers an effective and low-cost solution for millimeter-wave applications.

A coplanar millimeter wave doubler MMIC covering the entire G-band was developed. Based on a 50 nm metamorphic HEMT technology, the circuit demonstrates an output power of more than –12 dBm between 150and 220 GHz for an input power of 0 dBm. By increasing the input power to 12 dBm an output power exceeding 0 dBm was obtained in the frequency range between 180and 220 GHz. Good fundamental reject...
