A novel 80GHz sub-harmonic (x4) mixer has been designed and implemented. Mounting and ribbon bonding process is ongoing.

A Multiband, adaptive, radio-frequency (RF) transceiver architecture for carrier aggregation, has been developed, suitable for: 1) Demonstrate carrier aggregation of up to 5 components carriers (CC), 2) Demonstrate carrier aggregation of FDD and TDD, 3) Demonstrate carrier aggregation between licensed and unlicensed bands, 4) Demonstrate MIMO capabilities. Board has been developed and measurements are ongoing.
