Abstract: A Microwave power detector is coupled to a rectangular waveguide with a sidewall replaced by an uniform metallization on a bottom face of a FR4 dielectric substrate screwed to the waveguide. Two irises aligned along a common line parallel to the lines of magnetic field inside the waveguide, are etched inside the metallization acting as sidewall. Two microstrips are laid down on the upper face of dielectric substrate, each one intersects a respective iris orthogonally in the middle point. The two microstrips are connected to ground at one end immediately beyond respective irises, and are spaced substantially quarter wave apart calculated at the centre of the operating frequency band (15-18 GHz). Besides, the two microstrips are quarter wave long in order to show an open circuit impedance at the other end connected to a respective voltage detector including a Schottky diode in series to a resistor. At midpoint of the connection line between the two serially connected voltage detectors a voltage Vsum is read with high impedance. Vsum is the average of the two detected voltages, it is indicative of the signal power travelling across the waveguide and it results substantially insensitive of standing-wave pattern ( fig.12 ).

Abstract: A microwave power sensor is disclosed which is capable of using diodes above their resonant frequency to sense the power of input microwaves. The power sensor includes a sensing diode (34, 90, 90′), a conditioning means (30, 79), and a tapered waveguide. For input waves having frequencies near and above the resonant frequency of the sensing diode, the output of the diode begins to be frequency dependent. That is, the diode outputs different DC signals for waves having different frequencies even though the power of the waves is the same. The conditioning means is adapted to offset the frequency dependence of the diode by varying the fraction of the input wave that is transmitted to the diode so as to cause the output of the diode to be relatively constant for waves having equal power but different frequencies. The conditioning means also provides a load impedance which matches the characteristic impedance of the input wave to minimize the reflection of the input wave. In addition, the conditioning means attenuates the input signal to ensure that the sensing diode operates in the square law region. The tapered waveguide (32, 86) receives the wave transmitted by the conditioning means and conveys it to the sensing diode. The waveguide is adapted to cause the input wave to have a voltage maximum at its output port. By attaching the sensing diode across the output port of the waveguide, the power sensor is capable of sensing the power of input waves having frequencies over a broad frequency band.

Abstract: An ultrafast sampler includes a series of Schottky diodes configured with a coplanar waveguide to form a nonlinear transmission line (NLTL) that compresses a local oscillator input to form a series of strobe pulses. Strobe pulses of opposite polarity are capacitively coupled to sampling diodes to obtain samples of a signal applied to a signal input. The samples are directed along an intermediate frequency waveguide to, for example, a signal processor such as an oscilloscope, for storage and analysis. The intermediate frequency waveguide is configured so that conductors of the intermediate frequency waveguide receive signal samples of a common polarity and strobe samples of opposite polarities so that portions of strobe pulses delivered to a signal processor are distinguished from signal samples. In an embodiment, the intermediate frequency waveguide and the strobe waveguide are positioned between the axis and the conductors of the intermediate frequency waveguide. The sampling circuit is defined on a GaAs substrate and a coaxial-to-airline-to-substrate transition is configured to deliver signals from a coaxial cable to the sampling circuit. A signal output is configured to direct the signal back into a coaxial cable.

Abstract: Frequency converters include waveguides configured for a local oscillator (LO) signal, an intermediate frequency (IF) signal, and an RF signal. A multimode IF waveguide can be used for selectively coupling of an IF signal and to reduce signal contributions produced by the LO signal. Typically, the multimode waveguide is situated to that the IF signal and the LO signal propagate in different waveguide modes, and a selected one of these signals can be selectively attenuated. In some examples, a periodically stepped waveguide is used to enhance propagation of a selected waveguide mode or a lossy conductor is used to attenuate a selected waveguide mode.
