7928A Digital Phase Shifter by KRATOS General Microwave

The Model 7928A is a miniaturized, hermetically sealed PIN diode phase shifter that operates from 6 to 18 GHz providing a full 360° range of variable phase shift. It can also be used to perform frequency translation. The unit is an integrated assembly of an RF vector modulator and a driver circuit consisting of an 8-bit D/A converter and a voltage buffer. When used as a frequency translator, it has a translation rate of 0 to 500 kHz with carrier and sideband suppression levels of over 25 and 20 dB, respectively. This digital phase shifter has an insertion loss under 12 dB and a switching speed of less than 500 nsec. It can handle up to 30 dBm of input power and requires a 5 V supply. The phase shifter is available in a module with SMA M/F connectors.
