SigaTek Announces New Electronically Controlled
|
||||
January 18, 2012 Press Release
January 18, 2012 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. Visit website page for a complete line of
phase shifters.SigaTek microwave specializes in high quality, high frequency microwave communication components up to 65 GHz.
