Abstract: A frequency translating device (FTD) includes at least one mixer diode connected to down-convert a radio frequency (RF) to an intermediate frequency (IF) and to up-convert an IF to an RF and a source of direct current (DC) bias that is connected to the mixer diode. The source of DC bias provides DC bias to the mixer diode that moves the voltage applied to the mixer diode closer to the threshold voltage of the mixer diode. The mixer diode is turned on in response to the DC bias and a local oscillator (LO) drive. Because DC bias is applied to the mixer diode, the peak to peak voltage range of the LO drive can be reduced, thereby reducing the voltage-dependent capacitance of the mixer diode, causing the FTD to exhibit improved reciprocity. The FTD can be used in a three-pair measurement system to determine the conversion response of another FTD.

Abstract: An integrated circuit mixer which is impedance matched to a fundamental waveguide, utilizes a slot coupler and a coplanar transmission line to apply an RF and local oscillator signal to a Schottky-barrier diode. The IF signal which is available at the output of the Schottky-barrier diode is filtered by means of an RF bypass capacitor that is located on the dielectric substrate surface. At 110 GHz, a mixer module when mounted in the end of a waveguide horn, has an uncooled double-sideband (DSB) mixer noise temperature of 339.degree. K. and conversion loss of 3.8 dB.

Abstract: A carrier converting equipment to be used such as for the reception of a satellite television broadcasting signal by an ordinary television receiver by adding a very simple adapter for converting such satallite signal for instance a frequency modulated microwave signal into an amplitude modulated VHF wave signal. The frequency modulated receiving input wave is amplitude modulated by an amplitude modulation adding circuit in which the wave is modulated for instance to have larger amplitude at the higher frequency portion and smaller amplitude at the lower frequency portion. This amplitude modulated wave is supplied to a non-linear element together with a desired carrier frequency signal. The carrier frequency signal is amplitude modulated in accordance with the amplitude of the applied amplitude modulated signal due to conductance variation of the non-linear element.
