Digital Phase Shifter
4-Bit, 8.0 - 12.0 GHz
4 Bit Digital Phase Shifter
360° Coverage with LSB = 22.5°
Integrated CMOS Driver
Serial or Parallel Control
Low DC Power Consumption
Minimal Attenuation Variation over Phase Shift
50 Ω Impedance
Lead-Free 4 mm 24-Lead PQFN Package
The MAPS-010146 is a GaAs pHEMT 4-bit digital
phase shifter with an integrated CMOS driver in a
4 mm PQFN plastic surface mount package. Step
size is 22.5° providing phase shift from 0° to 360° in
22.5° steps. This design has been optimized to
minimize variation in attenuation over the phase shift
The MAPS-010146 is ideally suited for use where
high phase accuracy with minimum loss variation
over the phase shift range are required. The 4 mm
PQFN package provides a smaller footprint than is
typically available for a digital phase shifter with an
internal driver. Typical applications include
communications antennas and phased array radars.
