GENERAL DESCRIPTION
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.
