The ADRF5031 is a nonreflective, SPDT switch manufactured using the silicon on insulator (SOI) process. The ADRF5031 operates from 9 kHz to 20 GHz with an insertion loss of lower than 1.05 dB and isolation of higher than 45 dB. The device has an RF input power handling capability of 33 dBm average and 35 dBm peak for forward and reverse through paths, hot switching through the RFC port, and 30 dBm average and 32 dBm peak for terminated paths and hot switching through RFx ports. The ADRF5031 operates with dual-supply voltages of ±3.3 V. The ADRF5031 employs complementary metal-oxide semiconductor (CMOS) and low-voltage transistor to transistor logic (LVTTL)-compatible control.

The ADRF5031 can also operate with a single positive supply voltage (V_DD) applied while the negative supply voltage (V_SS) is tied to ground. In this operating condition, the small signal performance is maintained while the switching characteristics, linearity, and power handling performance are derated. See Table 2 for more details.

The ADRF5031 is pin compatible with the ADRF5023 and ADRF5027 and also pin compatible with ADRF5030, a fast switching version, which operates between 100 MHz to 20 GHz.

The ADRF5031 is packaged in a 20-terminal, 3 mm × 3 mm, RoHS-compliant, land grid array (LGA) and operates from −40°C to +105°C.
