Digital phase shifters

25 January 2012 Telecoms, Datacoms, Wireless, IoT

MA-COM Tech has announced the release of a new family of digital phase shifters with the initial introduction of two members.

The new GaAs pHEMT MAPS-010144 and MAPS-010164 are 4- and 6-bit packaged devices for use in S-band applications from 2,3 to 3,8 GHz. They maintain low phase error and low attenuation variation over the full 360° and frequency range.

The MAPS-010144 is a 4-bit phase shifter with a built-in CMOS driver that allows for serial or parallel control and low power consumption. The 360° phase shift is broken down to steps of 22,5°. It offers a low 2,5 dB insertion loss with a ±0,5 dB attenuation variation and a ±4,0° phase accuracy over the operating band.

The MAPS-010164 is a 6-bit device with built-in CMOS driver. It too is capable of either serial or parallel operation and the 360° of phase shift is divided into 5,6° step sizes. It has 3,2 dB insertion loss with a low ±0,6 dB attenuation variation and a ±5,0° phase accuracy over the entire band.

Both phase shifters operate using both positive and negative voltage supply. They are packaged in industry standard 4 mm, 24-lead PQFN style packages, and are intended for use in communication antennas, electronic warfare (EW) receivers, weather and phased array radar applications.
