Part details & applications

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 1.2 dB and isolation higher than 47 dB. The device has RF input power handling capability of 33 dBm for through paths, 18 dBm for terminated path, and 30 dBm hot switching at the RF common (RFC) port.

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 (V_DD) applied while the negative supply pin (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.

The ADRF5050 employs complimentary metal-oxide semiconductor (CMOS)- and low voltage transistor to transistor logic (LVTTL)-compatible controls.

The device has enable (EN) and logic select (LS) controls. Pulling EN pin to high activates all-off state while pulling LS pin high inverts the throw port selection logic, allowing ease of use for back-to-back applications. Please see the Theory of Operation section, Table 7 and the Back-to-Back Application section.

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.
