The Q175 Series are available in phase-matched sets and are factory tested for all unit-to-unit tracking requirements on a 100% basis. In addition to phase and amplitude repeatability, the Q175 Series provide low VSWR and axial ratio across the operating band.
The Q175 Series are available in a standard 3-hole mount (model Q175-3) or pinned to a precision mounting-bracket (model Q175-2) for direct installation in a customer supplied Interferometer housing. The latter configuration provides improved unit-to-unit phase tracking for high accuracy interferometer applications.
