Abstract: A double balanced mixer or modulator utilizing a hybrid junction in which the junction port of the isolated arm is equally excited by two arms connected in parallel to the excited input port. The hybrid junction is formed of compensated baluns which according to one embodiment are connected together with a star arrangement of diodes to form a bias/modulation port resulting in a double balanced mixer or modulator.

Abstract: Coaxial line apparatus forming a termination and detector for high frequency signals. An input coaxial transmission line has an inner conductor and an outer conductor. The input coaxial transmission line is branched into a load transmission line and a parallel video transmission line. The load transmission line has inner and outer conductors and a matching impedance connected between the inner and outer conductors for terminating the load transmission line. The parallel transmission line has a separate outer conductor and inner conductive means. The inner conductive means include a crystal diode mounted at an angle with respect to the axis of the parallel transmission line outer conductor. The parallel transmission line outer conductor has an apertured portion substantially aligned with the crystal diode so that the crystal diode can be inserted or removed through the apertured portion. The parallel transmission line also includes additional impedances for attenuating relatively high frequency signals.
