Sub-Harmonic resistive HEMT based mixers in Gband have been designed and integrated with Double Slot Antenna in Differential Configuration for the first time. This novel topology shows compact integration of active devices between antenna ports while achieving 25 GHz bandwidth around 200 GHz. The dual-gate 50nm x 15um InP HEMT used in the design achieves the conversion loss of 15 dB with +3 dBm LO power drive. Furthermore, a similar topology when used as a Harmonic mixer using a single gate device offers 16.5 dB conversion loss for +4 dBm LO power. For compact integration, via hole matching on slot antenna is also presented.
