Nonreflective, Silicon SP4T Switch, 100 MHz to 20 GHz

The ADRF5050 is a nonreflective SP4T switch manufactured in a silicon on insulator (SOI) process. The ADRF5050 operates from 100 MHz to 20 GHz with insertion loss less than 1.20 dB and isolation higher than 47 dB. The device has RF input power handling capability of 33 dBm for through paths.

The ADRF5050 operates with a dual-supply voltage +3.3 V and −3.3 V. The device can also operate with a single positive supply voltage (VDD) applied while the negative supply pin (VSS) is tied to ground. The single-supply operation condition requires lower operating power while the excellent small signal performance is maintained (see Table 2 in the data sheet).

The ADRF5050 employs complimentary metal-oxide semiconductor (CMOS)- and low voltage transistor to transistor logic (LVTTL)-compatible controls. The device has enable and logic select controls to feature all off state and port mirroring, respectively.

The ADRF5050 is pin compatible with the ADRF5042 and ADRF5043.

The ADRF5050 comes in a 24-terminal, 3 mm × 3 mm, RoHS compliant, land grid array (LGA) package and can operate from −40°C to +105°C.
