A balanced MMIC doubler implemented in a metamorphic HEMT technology is described. The multiplier is design for C-band (3/6 GHz), and it is based on 2x50 μm mHEMT transistors with common sources connected to ground through a parallel RC circuit. No external gate bias voltage supplies are needed due to the self bias effect of the RC circuit. The balanced doubler gives an output power of 8dBm @ 6 GHz with a power consumption of only 40mW. The 3dB bandwidth is 40 %. The fundamental frequency is suppressed more than 30 dB and the third and fourth harmonic is suppressed more than 20 dB in the desired BW. The agreement between measurements and simulations is good.
