8-Bit Programmable Digital Phase Shifters from 0.5 to 18 GHz

Fairview Microwave has introduced a new series of 8-bit programmable digital phase shifters that are adjustable over a full 360 degree range. The series consists of three models that can produce a discrete set of phase states of up to 256 total steps in 1.4 degree increments with excellent accuracy and minimal phase shift error. These digitally controlled analog phase shifters cover broadband microwave and millimeter wave frequencies from 0.5 GHz to 18 GHz. They are ideal building block components for aerospace and defense radar and EW applications involving phased-array antennas, phase discriminators, beam forming networks and RF communication systems.

The phase shifters feature an 8-bit TTL digital-to-analog converter that allows phase states to be precisely controlled. The integrated hybrid MIC design architecture provides greater immunity to noise on control lines, delivers more uniform performance from unit-to-unit and achieves a flatter phase response over a wider frequency bandwidth with higher power handling and improved linearity performance.

Typical phase shift error ranges from +/- 0.9 to +/- 4.5 degrees over 8 binary increments with fast switching speed performance from 30 to 265 nsec. Maximum input (CW) power varies from +13 dBm to +30 dBm, depending on the model. The packages are compact and environmentally sealed with field-replaceable SMA or 2.92 mm connectors, and sub-miniature D multi-pin connectors for the power/logic controls. These models are designed to meet MIL-STD-202F requirements for temperature cycle, humidity, shock, altitude and vibration.

The new 8-bit programmable phase shifters are in-stock and ready for immediate shipment with no minimum order quantity. For detailed information on these products, click here.
