摘要： A microstrip instantaneous frequency discriminator operable at frequenciesbove 18GHz. A first power divider divides the input signal into equal power outputs which are used as the inputs to second and third power dividers. One of the outputs from each of the second and third power dividers is used as the input to a 180.degree. hybrid and the other output from each of the second and third power dividers is used as the inputs to a 90.degree. hybrid. The outputs of the 90.degree. hybrid and the 180.degree. hybrid are subsequently processed to provide signals suitable for a visual polar display of the instantaneous frequency and power level of the input signal.

摘要： This invention is a resonant waveguide Stark cell suitable for use in a Stark-modulated microwave spectrometer. The cell is constructed from a short length of waveguide. A Stark electrode is located inside the waveguide parallel to the broad face of the guide and insulated from the walls of the guide with narrow teflon strips. A reflector with a small coupling iris at its center is located at one end of the cell. This small coupling iris is for passing microwave energy into and out of the cell. At the other end of the cell there is an adjustable waveguide short making the small Stark cell into a tuneable cavity which can be tuned for resonance at selected microwave frequencies. Means are provided for maintaining a gas-tight compartment within the cell, and ports are provided for the introduction of the gas to be analyzed into the gas-tight compartment.
