Part details & applications

The ADRF5238 is a high isolation, nonreflective, 0.1GHz to 13GHz, silicon, SPDT switch in the silicon process.

The ADRF5238 operates from 0.1GHz to 13GHz with an insertion loss lower than 1.3dB and an isolation higher than 41dB at 13GHz. The ADRF5238 has a nonreflective design and the RF ports are internally terminated to 50Ω. The device has input power handling capability of 35dBm for through path, 27dBm for terminated path and 33dBm hot switching at the RFC pin.

The ADRF5238 requires a single-supply voltage (V_DD) of 3.3V to 5V. The ADRF5238 employs 1.8V complementary metal-oxide semiconductor (CMOS)-compatible and 3.3V low-voltage transistor logic (LVTTL)-compatible controls. The ADRF5238 has an enable control to put both RF channels in an isolation state.

The ADRF5238 comes in a 12-lead, 2mm × 2mm, LFCSP_RT and can operate from −40°C to +105°C.
