MACOM MAPS-010166 GaAs pHEMT 6-Bit Digital Phase Shifter Product Overview

MAPS-010166 Product Introduction

The MAPS-010166 is a GaAs pHEMT 6-bit digital phase shifter from MACOM (formerly M/A-COM Technology Solutions), featuring an integrated CMOS driver and housed in a 4 mm 24-pin PQFN plastic surface-mount package. The device operates in the X-band frequency range from 8.0 GHz to 12.0 GHz, with a phase step of 5.6°, providing full phase coverage from 0° to 360°. It is specifically designed for high-frequency systems with stringent requirements for phase accuracy and loss consistency.

The MAPS-010166 optimises attenuation characteristics across the phase-shifting range, minimising insertion loss fluctuations. The 4 mm PQFN package offers a smaller board footprint compared to traditional digital phase shifters with built-in drivers, making it suitable for space-constrained phased array systems.

Typical Applications

The MAPS-010166’s X-band capability and compact package make it suitable for the following fields:

Phased-array radar: Used for beamforming and electronic scanning, enabling adjustment of the antenna array’s beam direction through precise phase control

Communications antenna systems: Including phase modulation and beam control in satellite communications and point-to-point microwave links

Aerospace and defence: Platforms with stringent requirements for reliability and environmental adaptability, such as military radars and ground-based ranging radars

Weather radars: Phase control units in commercial weather radars

The device’s high phase accuracy and low loss variation make it particularly suitable for systems requiring consistent signal amplitude across a wide phase range.
