Passive GaN Mixers Set Linearity Benchmark

Custom MMIC offers a technical brief outlining their progress with reaching incredible limits of linearity with passive MMIC mixers using GaN Technology. The company is exploring the use of gallium nitride (GaN) processes as the basis for highly linear RF mixers. Deducing that the high linearity performance of GaN power amplifiers may cross-over to other critical microwave components, Custom MMIC engineers have gone through several iterations of GaN mixer technologies and typologies with several of their key foundry partners.

 

This has led to passive GaN mixer designs that surpass all gallium arsenide (GaAs) passive mixer designs in terms of the ratio of input third-order intercept point (IIP3) to local oscillator (LO) drive -- a figure-of-merit Custom MMIC is coining as Linear Efficiency. From S-band to K-band (2 GHz to 19 GHz) these new passive GaN mixers are demonstrating IIP3 figures well above 30 dBm, LO drive levels around 20 dBm, and linear efficiencies above 10 dB.
