Pasternack, a leading provider of RF, microwave and millimeter wave products, introduces a series of 8-bit digital phase shifters which are programmable over a full 360° range and can produce a discrete set of phase states of up to 255 total steps with 1.4° increments with a high level of accuracy and minimal phase shift error. These building block components cover broadband microwave and millimeter wave frequencies and are ideal for aerospace and defense radar and EW applications which involve phased-array antennas, phase discriminators, beam forming networks and RF communication systems.
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 highly integrated hybrid MIC design architecture offers the benefit of greater immunity to noise on control lines and gives more uniform performance from unit to unit, achieves a flatter phase response over a wider frequency bandwidth with higher power handling and improved linearity performance.
Pasternack offers 4 new models of digital phase shifters which cover frequency bands that range 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 nsec. Maximum input (CW) power varies from +10 dBm to +30 dBm depending on the model. The compact packages are environmentally sealed and feature field replaceable SMA or 2.92mm connectors and sub-miniature D multi-pin connectors for the power/logic controls. Additionally, all models are designed to meet MIL-STD-202F conditions for temperature cycle, humidity, shock, altitude, and vibration, which give designers added confidence for high reliability operation.
“Our comprehensive selection of 8 bit digital phase shifters offer designers optimum response characteristics with programmable tuning accuracy that can be used for a variety of aerospace and defense applications,” explains Tim Galla, Active Components Product Manager at Pasternack.
