Abstract

A Gilbert micromixer is demonstrated in this paper using GaInP/GaAs HBT technology. By using an on-chip active LO balun, the micromixer with the single-ended RF. LO, and IF ports is suitable for hybrid RF system applications. The port-to-port isolation has its best performance when the LO signal is balanced. The fully matched high-linearity micromixer has the conversion gain of 12 dB, IP1dB of - 9 dBm, IIP3, of 1 dBm when f IF(input) = 300 MHz, fLO = 3.5 GHz, and f RF(output) = 3-8 GHz.
