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

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.
