Analog Devices Inc. ADRF5048 Non-Reflective SP4T Switch

Analog Devices Inc. ADRF5048 Non-Reflective SP4T Switch is manufactured using the silicon-on-insulator (SOI) process. This device operates from 100MHz to 45GHz with an insertion loss lower than 4.0dB and isolation higher than 35dB. The ADRF5048 has an RF input power handling capability of 30dBm through path, 18dBm terminated path, and 30dBm hot switching at the RF common port.

The Analog Devices Inc. ADRF5048 requires a dual-supply voltage of +3.3V and −3.3V. The device employs complementary metal-oxide semiconductor (CMOS)-/low-voltage transistor-to-transistor logic (LVTTL) logic-compatible controls. The ADRF5048 has enable and logic select controls to feature all off-state and mirror port selections, respectively. The ADRF5048 is pin-compatible with the ADRF5049, ADRF5042 and ADRF5043. The ADRF5048 comes in a 24-terminal, 3mm × 3mm, RoHS compliant, land grid array (LGA) package and can operate from −40°C to +105°C.
