The SMC-123284 from Scientific Microwave Corporation is an 8-bit digitally controlled waveguide phase shifter that operates from 2.60 to 3.95 GHz. It provides a phase shift from 0 to 360° with a resolution of 1.4° per bit, controlled digitally using an 8-bit codeword input. This phase shifter operates over a bandwidth of 0.2 GHz with an insertion loss of 0.3 dB. It can handle an average input power of 1.5 kW and a peak power of 40 MW with a VSWR of 1.15:1.
The SMC-123284 consists of a DB15 connector interface that accepts the 8-bit codeword input and a trigger signal to achieve the desired phase shift. It is based on a hybrid coupler with a movable short, using a WR284 waveguide interface, and requires an AC supply of 220 V. This digital phase shifter is ideal for precise phase control in critical phased array antennas, radar systems, and satellite communications.
