Full Band Phase Shifters
STP-18-10-M2
Full band phase shifters are micrometer-driven, waveguide-based phase shifters. The configuration of the micrometer-driven phase shifters is similar to that of level setting attenuators, where the phase shifting is caused by an E-plane dielectric insert in the rectangular waveguide. The amount of phase shifting is directly dependent on the volume of the insert. The VSWR and the insertion loss of these phase shifters are dependent on the frequency. The below standard offering covers the frequency range of 18 to 110 GHz and a phase shifting range of 180 degrees. These micrometer-driven phase shifters are typically used to introduce a certain amount of phase shifting when the absolute number is not a focus.

Conical Horn Antennas
Conical gain horns are offered as both standard and custom models with either a circular or rectangular waveguide interface. While conical gain horns with a rectangular waveguide interface can only support linear polarization, models with a circular waveguide interface can support various polarization types including horizontal, vertical, left-handed circular, and right-handed circular polarization for broader applications. The listed models operate across the full waveguide band and offer 23 dB nominal gain, 12 degrees typical half power beamwidth, a 24 dB typical side lobe level and 1.15:1 VSWR at center frequency. The below standard offering covers the frequency range of 8.5 to 140 GHz. However, other frequencies and standard models with 10, 15, 20 and 25 dB gain are also available.
