Abstract
A wafer type millimetric crystal holder of the Sharpless type with an impedance matched i.f. coaxial output. The connection between the i.f. coaxial output and the diode comprises two coaxial quarter wavelength stubs interconnected by a strip line element with a wire central conductor operating as a rejector at the carrier frequency. The diameter of the central conductor is determined by the impedance matching condition.
