Package Outline GENERAL SPECIFICATIONS Bandwidth: Modulation Rate: Impedance: Input Power: Control Voltage for full range: Response Time: (50 Ω source): Phase Stability, typical: Operating Temperature: 10% of fo 1% of fo nom. 50 Ω nom. -- 10 dBm max. 0 to +15 V max. 50 µs max. 0.2° per °C -- 55° to +85°C Typical Characteristics NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over mm. General Notes: 1. The PLB & PLM series use a control voltage of 0 to +15V to vary relative phase across a 180° range. 2. Each phase shifter element employs quadrature hybrids with matched pairs of varactor tuned LC networks acting as sliding short circuits on the outputs. The electrical length of this short circuit controls the delay in the reflected signal appearing at the isolated port of each quadrature hybrid. 3. These units are suitable for high reliability and space applications. 15Feb96 F rf t e if r to c n a tM ERRI AC /41 Faifel Pl,W estCal el,NJ,07006 / 973o ur h r n o ma in o t c M ri d . dw l 5751300 /FAX 973- 0531 575-
