These digitally controlled analogue phase shifters cover broadband microwave and millimetre wave frequencies. They are ideal building block components for aerospace and defence radar and EW applications involving phased-array antennas, phase discriminators, beam forming networks and RF communication systems. Fairview Microwave’s programmable phase shifters feature an 8-bit TTL digital-to- analogue 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. These three new programmable phase shifters cover frequency bands from 0.5 to 18GHz. Typical phase shift error ranges from ±0.9 to ±4.5° over 8 binary increments with fast switching speed performance from 30 to 265nsec. Maximum input (CW) power varies from +13dBm to +30dBm, depending on the model.
The packages are compact and environmentally sealed with field-replaceable SMA or 2.92mm 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.
“Designers can be confident in our comprehensive selection of 8-bit programmable phase shifters that deliver highly reliable operation and optimal response with extremely precise tuning accuracy that can be used for a variety of aerospace and defence applications,” said Randy Leenerts, Senior RF Engineer at Fairview Microwave.
