Covering the 9 kHz to 12.0 GHz range, the switch offers high isolation and low insertion loss. The switch features 34 dB isolation and 0.8 dB insertion loss up to 8.0 GHz, and a 9 µs settling time of 0.05 dB margin of the final radio frequency output (RFOUT). The switch operates using positive contro...
