This paper introduces a design of power amplifier operating at non-atmosphere window waveband,which can be used as short distance detection system on missiles.The circuit designed for this power amplifier is based on MMIC.It uses double electric bridge which has better standing wave at ports,and the power combination is realized by multiple cascading.From waveguide to microstrip,microstrip probe is employed and inserted through E-plane of the waveguide,realizing the transition between double waveguide solid transmission line and microstrip integrated transmission line,and the in-phase wideband power combination/divider.Practical measurements show that at operating bandwidth,the specifications have met the requirements of the design,and larger power output has been realized,thus providing technical assurance for engineering application.
