A 60 GHz double balanced sub-harmonic mixer MMIC

We present the design and measured results for a 60 GHz double balanced sub-harmonic MMIC mixer fabricated using the TRW 0.15mm gate length GaAs pHEMT foundry process. The sub-harmonic mixer architecture eliminates the need for costly mm-wave sources that are usually required with conventional fundamental frequency mixers. The mixer has been integrated into a coaxial package and a measured conversion loss of less than 10 dB across the 53 GHz to 60 GHz frequency band has been obtained. This conversion loss is believed to be approximately 2 dB better than previously published results.
