Model SF29A7 is a voltage-controlled phase shifter for applications from 150 to 300 MHz. It provides continuous phase adjustment range of 0 to 360 deg. with tuning voltages of 0 to +20 VDC, featuring maximum VSWR of 1.90:1 and maximum insertion loss of 4 dB across the operating frequency range. Available in surface-mount housings and packages with coaxial connectors, the component is part of a full family of phase shifters spanning 1 to 2500 MHz. Among these is model SF31A7, which provides a full 360-deg. control range from 1800 to 2000 MHz via control voltages from 0 to +20 VDC. It offers maximum VSWR of 1.90:1 and maximum insertion loss of 4.4 dB across its operating bandwidth. The firm also offers octave-band phase shifters with 180-deg. control ranges.
