Digital phase shifters

25 July 2012 Analogue, Mixed Signal, LSI

M/A-COM Technology Solutions has added two new members to its digital phase shifter product family.

These GaAs pHEMT MAPS-010145 and MAPS-010165 are 4- and 6-bit packaged devices for use in C-band applications from 3,5 to 6,0 GHz. They maintain low phase error and minimal attenuation variation over the full 360 degrees and frequency range.

The MAPS-010145 has a built-in CMOS driver that allows for serial or parallel control and low power consumption. The 360 degree phase shift is broken down to steps of 22,5 degrees. It offers insertion loss of 5,0 dB with a ±1,0 dB attenuation variation and high phase accuracy over the operating band.

The MAPS-010165 also has a built-in CMOS driver and is capable of either serial or parallel operation, while the 360 degrees of phase shift is divided into 5,6 degree step sizes. It has 5,5 dB of insertion loss with a low ±0,8 dB attenuation variation and high phase accuracy over the entire band.

The phase shifters operate using both positive and negative voltage supply. They are packaged in industry standard 4 mm, 24-lead PQFN style packages. They are intended for use in commercial weather radar and military phased array radar applications.
