4 × 4 ring array antennas are combined with commercially available and custom designed RF components to realize a base station operating for channel #1 of UWB communications. The 4 transmitters and receivers modules are developed using LNA, PA, buffer amplifiers, custom designed single and dual GCM mixers, and differential BPF and LPF. The GCM mixer is driven by a StLO poly-phase board that is realized using stable LO, PA, custom designed poly-phase circuit and 1:2 power divider/Baluns at 3.158 GHz.
