The ADRF5448 is a nonreflective, SP4T switch manufactured in the silicon process attached on a gallium arsenide (GaAs) carrier substrate. The substrate incorporates the bond pads for chip and wire assembly, and the bottom of the device is metalized, connected to ground.

The ADRF5448 operates from 100 MHz to 45 GHz with insertion loss less than 3.5 dB and isolation higher than 40 dB. The device has an RF input, power handling capability of 29 dBm for the through path, 17.5 dBm for the terminated path, and 29 dBm for the hot switching.

The ADRF5448 requires a positive supply (VDD) of +3.3 V and a negative supply (VSS) of −3.3 V. The device employs complementary metal-oxide semiconductor (CMOS)-/low-voltage transistor to transistor logic (LVTTL)-compatible controls.

The ADRF5448 is designed to match a characteristic impedance of 50 Ω and can operate from −40°C to +105°C.

APPLICATIONS

  • Industrial scanners
  • Test instrumentation
  • Cellular infrastructure mmWave 5G
  • Military radios, radars, and electronic counter measures (ECMs)
  • Microwave radios and very small aperture terminals (VSATs)
