Design and Implementation of a Leadless Packaged SPDT PIN Switch

According to our GaAs PIN diode process, we have successfully implemented a highly integrated, broadband, leadless PIN switch. In the 10GHz∼18GHz frequency band, the port stand wave is lower than 1.3, the insertion loss is less than 1.5dB, the isolation is greater than 25dB. The package size is limited to 4.0mm*4.0mm*1.2mm. The development of leadless package SPDT PIN switch will improve the technique of higher integration, lower system cost and smaller array area.
