A low loss series power combiner using suspended striplines

摘要

This report proposes a combiner which consists of suspended stripline couplers in series with additional parallel capacitance's. The capacitance's compensate the difference of phase velocities between the even-mode ami the odd-mode in the suspended stripline couplers. The fabricated combiners have realized good performances in insertion loss which is less than 0.3 dB over a bandwidth of 10 in the S-band.
