Abstract: The present invention provides an electrical circuit component, specifically a passive microwave device, and a method for producing the same. In one embodiment, the present invention provides an electrical circuit component, comprising: at least one patterned resistive area on a first surface of a diamond substrate, a first patterned conductive area on the first surface of the diamond substrate, and a second patterned conductive area on a second surface of the diamond substrate. The patterned resistive area may comprise a very thin film of tantalum nitride or a very thin film of tantalum nitride and a thin film of nichrome. The patterned conductive area may comprise a layer of titanium-tungsten, a layer of gold, and optionally a layer of nickel. Alternatively, the patterned conductive area may comprise a layer of chrome, a layer of copper, a layer of gold, and optionally a layer of nickel.

Abstract: The present invention is an absorptive-type cable temperature and frequency equalizer that offsets changes in the gain of the other circuit components cables with increases in temperature and/or frequency. The equalizer comprises a temperature variable filter network having component values and a temperature coefficient of resistance that vary over temperature and frequency to produce a desired response. The temperature and frequency equalizer has at least one thick film thermistor connected in series with a quarter wavelength transmission line. The thermistor absorbs forward and reflected signals at lower frequencies.
