A programmable slewing power supply is used to drive microwave phase shifters according to a command signal from a system controller using: a Milberger converter; a power source; a rectifying circuit; two differential amplifier circuits; and two comparator amplifier circuits. The Milberger converter outputs a combined square wave which it produces by combining two independent square waves which add or cancel. The power source receives the combined square wave and outputs: a reference voltage, a positive voltage signal; and a negative voltage signal. The rectifying circuit produces a rectified command signal by rectifying the command signal from the system controller. The two differential amplifier circuits respectively measure the positive and negative voltage signals with respect to the reference voltage to produce a measured positive voltage signal, and a measured negative voltage signal. The comparator operational amplifiers produce complementary outputs to drive the phase shifters by respectively comparing the measured positive and negative voltage signals with the rectified command signal.

In one embodiment, the invention is a packaged high power electronic switch in the form of a semiconductor chip having metalized planar cathode and anode terminals and a gate terminal. A refractory annular ring has planar open end faces and side walls having stepped portions. A pair of thermally and electrically conductive planar substrates is bonded to the opposite end faces of the annular ring and is maintained in spaced relation thereby, forming an enclosed space. At least one conductive strap within the space is supported by the stepped portion of the internal side wall and extends to one of the substrates forming an electrical and thermal path. One of said conductive substrates receives one of the planar terminals of the chip in intimate electrical and thermal contact. The strap is electrically coupled to the other of said terminals, for forming a high current path between the substrates via the strap. Additional components, such as a commutating diode and gate protection zener diode, may be employed and provide a self protected switch assembly.

A high voltage pulse regulator which is capable of measuring and correcting voltage perturbations on the top of a high voltage square wave pulse is disclosed. The regulator uses: a rectifying diode, an oscilloscope, a variable zener diode, a variable biasing current source and pulse capacitor. The rectifying diode receives and rectifies the high voltage square wave pulse from a high voltage pulse source to produce a rectified square wave pulse. The rectified square wave pulse is received and regulated to a voltage level acceptable to the oscilloscope by the variable zener diode pulse capacitor, and current source, which are connected together in a parallel circuit and act as follows. The variable zener diode is activated by the biasing current. Therefore, when there is no biasing current, the pulse capacitor and rectifying diode act as a peak detector, and the high voltage square wave pulse is adjusted down within a threshold of detection by the oscilloscope, when a bias current is applied to the variable zener diode, a threshold detector is established which permits the top of the pulse to be viewed on the oscilloscope display.

A solid state circuit breaker utilizing fast acting solid state relays which are made up of individual switching circuit modules using silicon metal oxide semiconductor field effect transistors or silicon carbide metal oxide semiconductor field effect transistors. Depending on the power requirements, the individual modules may be arranged to provide heat dissipation while at the same time minimizing the total overall space occupied in the circuit breaker.

The disclosed system comprises a testing system which measures the stability of a moving target indicator radar transmitter. It automatically measures the imperfections of its internal in-phase (I)/quadrature (Q) demodulator, and it consists of a control computer, a synchronizer, a frequency synthesizer, an IQ demodulator, a low noise amplifier and a waveform recorder. A unit under test is inserted across the test set for measurement and calibration. The system set has the following features: (a) An automatic calibration routine that requires a tunable RF source. This source provides the RF drive to the UUT. (b) A discontinuous analog to digital (A/D) sample clock that has a precise controllable relationship with the RF pulse. The A/D sample clock samples only during the presence of the RF. (c) A method for computing stability using a table of amplitude and phase weighting coefficients and pulse positions.

This high voltage linear FET amplifier operates at voltage levels of ten's of thousand's of volts with power dissipation capabilities in the kilowatt range. It is a broadband device which features power amplification from DC to frequencies well in excess of 100 KHz. The amplifier uses a unity-gain inverting amplifier as its basic building block. N-number of these building blocks are stacked to accommodate whatever voltage stand-off level is desired. To operate stacked high voltage amplifiers, it is necessary to provide a bias shift (reference) progressively increasing in equal increments from the ground reference stage to the highest voltage level stage while preserving the fidelity of the signal applied to the first stage. This is done by establishing a phantom ground at all amplifiers for each progressive bias level.

A field effect transistor (FET) quadrature switch for the control of multi mode microwave phase shifters provides bi-directional random mode switching while using only one power supply. The switch apparatus provides high speed, high voltage, and high-current switching while reducing the stand off voltage requirement of the linear driver, the number of switching elements which are required for mechanization, and reducing the size, weight and the complexity of the apparatus.
