A compact size Ka band pHEMT MMIC frequency tripler using lump element balun

This work presented a compact size Ka band pHEMT MMIC frequency tripler that incorporates a simple LC-lumped balun. The configuration not only can provide a flexible way to control the phases but also can reduce the chip size of the MMIC. As compared to the third harmonic frequency, the fundamental and second harmonic frequency can be suppressed more than 24 dB.
