High Isolation, Silicon SP4T, Nonreflective Switch, 9 kHz to 12.0 GHz

The ADRF5040 is a general-purpose, broadband high isolation, nonreflective single-pole, quad-throw (SP4T) switch in an LFCSP surface-mount package. 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 control voltage of 3.3 V and 0 V and requires +3.3 V and −3.3 V supplies. The ADRF5040 is packaged in a 4 mm × 4 mm, surface-mount LFCSP package.
