High power broadband GaN switch MMICs

In this contribution, design and characterization of two broadband GaN MMIC switches are presented. Being designed for a bandwidth of 5 to 18 GHz, both switches reach a minimum insertion loss of 0.7 dB and a maximum of 1.3 dB resp. 1.4 dB. Isolation values of more than 21 dB resp. 27 dB are realized. Loss compression is less than 1 dB at 43 dBm, resp. 0.5 dB at 42 dBm. Further large signal characterization has been performed to indicate potential use of limiting functionality of the switches.
