3-way low loss phase combiner for power amplifier sharing in 3-sector cellular networks
A low loss 3/spl times/3-way phase combiner for power amplifier load balancing in 3-sector wireless network cells is presented. Based on an air-filled coaxial double ring structure this design combines very low insertion loss with compact physical profile. Exemplary, the concept is studied for the PCS (personal communication service) transmit band from 1.91 GHz to 1.99 GHz by simulations. Measurements validate the predicted very low insertion loss of 0.05 dB, while return loss and port isolation are both better than 25 dB.
