RF and microwave digital phase shifters for radar and EW uses introduced by Pasternack

IRVINE, Calif., 3 Dec. 2015. Pasternack Enterprises Inc. in Irvine, Calif., is introducing a series of 8-bit RF and microwave digital phase shifters for aerospace and defense radar and electronic warfare (EW) applications involving phased-array antennas, phase discriminators, beam forming networks, and RF communication systems.

The phase shifters that cover broadband microwave and millimeter wave frequencies are programmable over a 360-degree range and can produce a discrete set of phase states to 255 total steps with 1.4-degree increments with a high level of accuracy and minimal phase shift error.

Pasternack's digital phase shifters offer the advantage of having a programmable 8 bit TTL logic interface where phase states can be precisely controlled.

The hybrid MIC design architecture offers immunity to noise on control lines and gives more uniform performance from unit to unit, and offers a flat phase response over a wide frequency bandwidth with higher power handling and improved linearity performance.

Pasternack offers four new models of digital phase shifters that cover frequency bands from 0.5 to 37 GHz. Typical phase shift error ranges from +/- 0.9 to +/- 5 degrees over 8 binary increments with fast switching speed performance from 30 to 450 nanoseconds.

Maximum continuous-wave input power varies from +10 dBm to +30 dBm. The compact packages are environmentally sealed and have field-replaceable SMA or 2.92-millimeter connectors and sub-miniature D multi-pin connectors for the power and logic controls.

All models are designed to MIL-STD-202F for temperature cycle, humidity, shock, altitude, and vibration. For more information contact Pasternack online at www.pasternack.com.
