M/A-COM Tech adds S-band digital phase shifters

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies for RF, microwave and millimeter-wave applications), has launched a set of S-band digital phase shifters for communications, electronic warfare (EW), and radar applications. The firm says that the phase shifters, which are housed in 4mm 24-lead PQFN packages and controlled with a single +5.0 V serial or parallel control line, facilitate easy implementation in communication antennas, phased array radars, weather radars, and EW receivers.

Specifically, the S-band gallium arsenide (GaAs) pHEMT 4-bit and 6-bit digital phase shifters meet the high-performance requirements of communications and radar system manufacturers, optimizing for fast switching speed, low phase error, and serial or parallel control capability, adds the firm.  

“M/A-COM Tech’s new 2.3-3.8GHz digital phase shifters maintain low phase error and low attenuation variation over the 360° range,” says product manager Kevin Harrington. “The built-in CMOS driver allows for serial or parallel control while in a small form factor,” he adds.

The MAPS-010144 4-bit digital phase shifter provides 360° phase shift range with a step size of 22.5°. Insertion loss is 2.5dB, with a low +/- 0.5dB attenuation variation and +/-4.0° phase accuracy over the 2.3-3.8GHz frequency range.

The MAPS-010164 6-bit digital phase shifter provides 360° phase shift range with a step size of 5.625°. Insertion loss is 3.2dB, with a low +/-0.6dB attenuation variation and +/-5.0° phase accuracy over the 2.3-3.8GHz frequency range.
