Latest Patents
John Clarke holds a patent for a Modular Solid State Radar Transmitter. This invention features a modular design that extends into the transmitter itself. The transmitter is composed of multiple power modules, with the number of modules selected based on the specific power needs of various applications. For instance, two 75 to 100 watt modules may be utilized for weather radar, while a larger configuration of 30 to 60 modules may be necessary for military fire control systems. The design includes a radio frequency signal from a stabilized local oscillator, which is distributed to the power modules via a splitter. A combiner is then used to merge the outputs from these modules, resulting in the final transmitter output signal. Each power module consists of parallel-connected power amplifiers, preferably using GaAs FETs, along with a power conditioning and control unit that manages the DC bias across the FETs to generate the desired signal. The transmitter can produce various output signals, including rectangular and Gaussian on a pedestal, as well as single amplifier outputs for testing purposes.
