C-band digital phase shifters deliver fast switching and low phase error

April 29, 2012 // By Jean-Pierre Joosting
M/A-COM Technology Solutions has introduced two additions to its family of digital phase shifters for radar, communication, and electronic warfare (EW) applications.

The phase shifters facilitate easy implementation in communication antennas, phased array radars, weather radars, and EW receivers. The 3.5 GHz to 6.0 GHz 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.

The MAPS-010145 is a 4-bit digital phase shifter housed in a 4-mm 24-lead PQFN package. It provides 360° phase shift range with a step size of 22.5°. It is controlled with a single +5.0 V serial or parallel control line. Its insertion loss is 5.0 dB, with a low ±1.0 dB attenuation variation and ±2.5° phase accuracy over the 3.5 GHz to 6.0 GHz frequency range.

The MAPS-010165 is a 6-bit digital phase shifter housed in a 4-mm 24-lead PQFN package. It provides 360° phase shift range with a step size of 5.625°. It is controlled with a single +5.0 V serial or parallel control line. Its insertion loss is 5.0 dB, with a low ±0.8 dB attenuation variation and ±5.2° phase accuracy over the 3.5 GHz to 6.0 GHz frequency range.
