GENERAL DESCRIPTION

The ADRF5250 is a general-purpose, single-pole, five-throw

(SP5T), nonreflective switch manufactured using a silicon

process. The ADRF5250 is available in a 4 mm × 4 mm, 24-lead

lead frame chip scale package (LFCSP) and provides high

isolation and low insertion loss from 100 MHz to 6 GHz.

The ADRF5250 incorporates a negative voltage generator to

operate with a single positive supply voltage from 3.3 V to 5 V

applied to the VDD pin when the VSS pin is connected to

ground. The negative voltage generator can be disabled when

an external negative supply voltage of −3.3 V is applied to the

VSS pin. The ADRF5250 provides a 1.8 V logic-compatible,

3-pin control interface.
