Abstract

A 7/21GHz frequency tripler, using a commercially available packaged pHEMT, was designed and fabricated on 15mil RO3003 substrate. Frequency conversion is realized using the third harmonic current of an class B amplifier with rejection feedback at fundamental with optimum load conductance at the third harmonic. The fabricated frequency tripler has achieved a conversion loss of 0.7dB for an input power of 0dBm at 21GHz. The experimental results show good agreement with the harmonic balance simulation.
