MAPS-010143-TR0500

The MAPS-010143 is a GaAs pHEMT 4-bit digital phase shifter with an integral 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 range.  The MAPS-010143 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 fora digital phase shifter with an internal driver.  Typical applications include communications antennas and phased array radars.
