Title: Kirk A Snodgrass: Innovator in Microwave Technology
Introduction
Kirk A Snodgrass is a notable inventor based in Phoenix, AZ. He has made significant contributions to the field of microwave technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Discrete Step Microwave Attenuator." This invention features a step attenuator that comprises two branchline couplers with two coupling transmission lines in between. Attenuation is achieved through switchable resistors, which are in series with switching diodes, shunted across the transmission lines. These resistors reflect and absorb incident power, while switching signals are provided to the diodes through the branchline couplers and coupling transmission lines. The reflected power is absorbed by a matched termination at the port of the input branchline coupler, which is isolated from the port at which the signal to be attenuated is coupled. Phase shift and insertion loss are minimized by tuning the series inductance inherent in the diode resistor combination with tuning capacitors in series. These capacitors are bypassed by low-susceptance inductors that provide a DC path to ground for the diodes.
Another significant patent is the "RF Power Amplifier for Use with VHF Transceivers." This improved power amplifier is particularly useful with very high frequency (VHF) transceivers. The power amplifier includes a control loop that senses the input radio frequency signal and uses that signal as a reference for comparison with the radio frequency output from the amplifier to control the amplifier's power output. The loop forces the amplifier's output radio frequency envelope to follow the input radio frequency envelope, thus producing a constant gain loop. A limiter in the loop ensures that the output remains at a constant power level when the input signal exceeds a predetermined threshold.
