Abstract
Abstract A millimetric mixer package is fabricated in block construction manner of inexpensive lightweight materials such as plastics, after which the surfaces to be conductive are gold-plated. An integral collection box forms a part of the package, for the disposition of a circuit board and other elements in the output end of the mixer. The mixer provides a hybrid junction of magic T type for 2 millimeter wave inputs, one of which may be a local oscillator, the junction being coupled by way of a resultant balanced output signal to impedance matching ramp elements, at the output end of which are disposed biased diodes which are adjustably positioned for optimum noise figure. The conductors providing the diode bias terminate at a circuit board in the collection box whereat the difference frequency signal output may be taken.
