A new series of 8-bit programmable phase shifters are adjustable over a full 360º range. These three new models can produce a discrete set of phase states of up to 256 total steps in 1.4º increments with superior accuracy and minimal phase shift error. These digitally controlled analog phase shifters cover broadband microwave and millimeter wave frequencies. 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. These programmable 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. They cover frequency bands from 0.5 to 18 GHz. Typical phase shift error ranges from +/-0.9 to +/-4.5º over 8 binary increments with fast switching speed performance from 30 to 265 nsec. Maximum input (CW) power varies from +13 to +30 dBm, depending on the model.
