GENERAL SPECIFICATIONS Phase Shift Range: 360° min. @ f o Insertion Loss: 2 dB max Impedance: 50 Ω nom. VSWR: 1.6:1 max. Control Voltage: 0.5 to +30V min.* Modulation Rate: 1% of f o nom. Input Power: -- 10 dBm max. Phase Stability: 0.2° per °C typ. Weight, nominal: 2.5 oz (72 g) Operating Temp: -- 55° to +85°C *For full control range General Notes: 1. The PSES-4 series of phase shifters provides continuously variable phase shift across a range of 0 ° to 360 ° with the application of a control voltage of 0 to +30V. 2. Each phase shifter element employs lumped element quadrature hybrids with matched pairs of varact or tuned LC networks acting as sliding short circuits on the outputs. The electrical length of the short effectively delays the reflected signal which appears at the isolated port of each quadrature hybrid. Similar Phase Shifters are available in a variety of packages, including catalog models in flatpacks and Meri-Pacs. 3. Merrimac phase shifters are designed for high reliability and can be supplied screened to meet sp ecific military and space applications. 24May96 NOTES: 1.
