          SigaTek microwave introduces new additions to the product line. Analog phase shifters covering the frequency range of 10 – 2500 MHz. Bands covered are octave and 10% bands. Also custom designs are available to meet any frequency and phase shift. Applications of these phase shifters are microwave systems that require voltage controlled phase shift.

          SigaTek offers a big selection of microwave components covering the frequencies  DC - 80 GHz: Power dividers, directional couplers, 90 and 180 degree hybrids, microwave mixers, frequency doublers, bias tees, I Q modulators, demodulators, image reject mixers, analog phase shifters, coaxial load terminations, connectors and adapters.   These phase shifters are designed using lumped elements components. Use of quadrature hybrids ( power dividers 90 degree) with a matched pair of LC networks  connected at the two outputs of the hybrid. The resonant frequency of the LC network (varactor diode and high Q fixed inductor) is adjusted with the controlled voltage resulting in constant amplitude (ideally) and varying phase 0 -180 degree across the frequency of operation. Two devices can be connected in series to give a resulting phase shift of  0 - 360 degree. Control voltage is 0 – 20 Vdc SigaTek phase shifters are with SMA connectors.
