Digital controlled Phase Shifters

Digitally Controlled Phase Shifters are devices that adjust the phase of microwave signals through Digital control. The basic principle is to use digital signal processing technology to sample and quantify the input analog signal or digital signal, and then digitize it. Then the phase of the signal is moved by digital signal processing device. the main indexes include operating frequency band, phase range, control bits, phase flatness, phase accuracy, insertion loss, voltage standing wave ratio, power capacity and so on.

Their features include:

1.High degree of automation: programmable or can be controlled through the computer interface, without manual intervention, improve system reliability and stability. In this case, as a two-state device, digital control phase shifter has different insertion phases at different states and microwave frequencies.
2. Flat phase can be maintained even on wide bandwidths..
3 .even if ,digital phase shifter is built into a network with poor impedance matching, it is not easy to phase traction.
4. not affected by the noise in the control line.
5.match higher power and linearity.

Because of the above characteristics, Digital Step Phase Shifter is widely used in communication, radar, radio frequency measurement, military equipment, etc., with the following application directions:

1.Provide a controlled phase difference for RF signals
2. Change the transmission phase Angle of a two-port network
3. The phase of radar phased array antenna and directional controllable communication link is controlled. The relative phase of each element of the elimination loop of a high linearity amplifier is controlled.
4. Beamforming.
5. Signal cancellation.

Qualwave supplies low insertion loss and high power manual phase shifters from DC to 40GHz. The phase adjustment is up to 360°/GHz, Connector types are SMA and 2.92mm. And the average power handling is up to 100 watts.
