Our new series of 8-bit digital phase shifters which are programmable. The Pasternack digital phase shifter series has over a full 360° range and can produce a discrete set of phase states of up to 255 total steps. These digital phase shifters steps with 1.4° increments with a high level of accuracy and minimal phase shift error.

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. This phase shifter line achieves a flatter phase response over a wider frequency bandwidth with higher power handling and improved linearity performance.

These digital phase shifters 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 using a grey epoxy paint finish and feature field replaceable SMA or 2.92mm connectors and sub-miniature D multi-pin connectors for the power/logic controls. Additionally, all these phase shifter 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.
