An ultra-wideband double-balanced resistive mixer with high dynamic range (IIP3) is reported. The mixer is designed and fabricated using HRL Laboratory's GaN high electron mobility transistor (HEMT) (T2) process and it utilises a series resistor-capacitor circuit network termination to the device gate, in order to achieve resonance-free broadband conversion loss and high dynamic range. The measured conversion loss from 3 to 40 GHz is between 5.5 and 8.5 dB at 1 GHz intermediate frequency. Large signal testing at 15 GHz showed a 1 dB gain compression point (P1dB) of 22 dBm. © The Institution of Engineering and Technology 2014.
