Analog Devices Inc. ADRF5050 Nonreflective Silicon SP4T Switches

Analog Devices Inc. ADRF5050 Nonreflective Silicon SP4T Switches implement a silicon-on-insulator (SOI) process. The device performs from 100MHz to 20GHz with an insertion loss of less than 1.20dB and isolation higher than 47dB. The ADRF5050 features an RF input power handling capability of 33dBm for through paths.

The ADI ADRF5050 nonreflective silicon SP4T switches have a +3.3V and -3.3V dual-supply voltage operation. Additionally, the device operates with a single positive supply voltage (VDD) applied while the negative supply pin (VSS) is tied to the ground.

The ADRF5050 utilizes compatible controls with complementary metal-oxide semiconductor (CMOS)- and low-voltage transistor-to-transistor logic (LVTTL). The device includes enable and logic select controls to feature all off-state and port mirroring.

The ADRF5050 is pin compatible with the ADRF5042 and ADRF5043 and is available in a 24-terminal, 3mm × 3mm, RoHS compliant, land grid array (LGA) package and operates from -40°C to +105°C.
