摘要：
E-band communications are unique in terms of data throughput capabilities which in turn make them crucial for the 5G network evolution. Unfortunately, they suffer from severe path loss and limited output power of commercial power amplifiers. This manuscript presents a prototype of 8-way paralleled solid state power amplifier fed by a waveguide division/recombination network. The wideband and low-loss features of the feeding network are proven across the whole E-band and are achieved by adopting an ad-hoc magic-tee structure. The OP1dB enhancement target for the manufactured sample is +7dB within 71-76 GHz and experiments show a linear gain of 14.6 dB at 73.5 GHz. The entire system has also been tested with a modulated signal.
