A K-band MMIC filter based on GaAs IPD technology

Abstract

This paper develop a high performance K-band Hair-Pin MMIC band-pass filter which is based on GaAs IPD technology. The measurement result shows that at the operation frequency of 19.5～21.3 GHz, the insertion loss of this filter is below 2.6 dB, the minimum insertion loss is 2.2 dB@20 GHz, and the return loss and group delay ripple of this filter is below -25 dB&50 ps in band. The test result is quite coincide with simulation. The size of the MMIC filter is only 2.96 mm×1.8 mm×0.1 mm, it has much less volume than the filter which is fabricated by traditional technology,and it is suite for the miniaturization trend of microwave device used in radar and communication system which has wide prospect of application.
