The TTI-FEED-Ka-300400-DC-A-V1 from TTI is a Dual Circular-Polarized Corrugated Cylindrical Horn (DC-CCH) that operates from 30 to 40 GHz. It is based on cylindrical waveguide horns with several axial choke corrugations. This horn provides a gain of 13 dB and has a VSWR of less than 1.5:1. It has a cross-talk of 22 dB between ports and a cross-polar discrimination of 26 dB (at boresight). This cylindrical horn has rotationally symmetric radiation patterns with low back radiation and very low cross-polarization. It has integrated polarizers and ortho-mode transducers with very low cross-coupling. It also includes high-precision customized mounting interfaces with levels and absorber plates.
The TTI-FEED-Ka-300400-DC-A-V1 is available with K-type (2.92mm) connector and is ideal for compact antenna test range feeds, spherical near-field antenna test range feeds, far-field antenna test range sources, and high-efficiency dual polarization reflector feed applications. Each horn includes high-precision customized mounting interfaces with levels and absorber plates.
