An apparatus and a method for dispersing particulate materials prone to agglomeration, in a liquid. Particulate materials are exposed to a liquid and put into that liquid to form a suspension or a dispersion in a controlled method thereby minimizing agglomerates. The method uses mechanical/hydro mixing that prevents the physical deterioration of the particulate material and inhibits agglomeration of the particles. In many cases, these materials may be nanomaterials. Almost all particulate materials, can be handled in this manner. This method has been found to be especially useful for preparing solutions of exfoliated graphene and certain drugs.

A solid state amplifier for a microwave transmitter includes a power divider wherein a signal to be amplified is divided into signals of equal signal levels. The equal level signals are respectively coupled to a plurality of amplifiers wherefrom the amplified signals are coupled to a combiner wherein the amplified signals are added and signal sum provided at an output terminal of the combiner. Each of the amplifiers may be comprised of a first stage amplifier, the output signal of which is coupled to a multiplicity of component amplifiers which, in tern, are coupled to a the output terminal of the first stage amplifier via a second power divider wherefrom signals of equal level are provided to the component amplifiers. Bias voltages are provided to the amplifiers via a modularized power supply having some modules with redundant converters.

Broadband, monolithic, planar m.times.m and m.times.n transfer switches with diode switching elements are disclosed. Symmetry of the switches maintain equal insertion amplitude and phase performance. Compensation of phase unbalance caused by diode parasitic capacitance is provided by inductors serially coupled between the diodes and the input and output terminals of the transfer switch. Stripline transmission lines are utilized and isolation between the transmission lines is provide in regions of stripline cross over in the plane.
