Analog Devices Inc. ADRF5023 Silicon SPDT Switches

Analog Devices Inc. ADRF5023 Silicon SPDT Switches are non-reflective, single-pole, double-throw (SPDT) switches manufactured in the silicon process. The ADRF5023 provides a 9kHz to 45GHz operating range with a typical insertion loss of 1.7dB and isolation of 42dB. The switches feature an RF input power handling capability of 30dBm for the through path, 24dBm for the terminated path, and 30dBm for the hot switching at the RF common port. The devices need a positive supply of 3.3V and a negative supply of -3.3V. The ADRF5023 utilizes complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls.

The ADI ADRF5023 silicon SPDT switches also operate with a single positive supply voltage (VDD) applied while the negative supply voltage (VSS) is tied to the ground. The small signal performance is maintained in this operating condition while the switching characteristics, linearity, and power handling performance are derated.

The ADRF5023 is housed in a 20-lead, 3.0mm x 3.0mm, RoHS-compliant, land grid array (LGA) package and operates from -40°C to +105°C.
