Latest Patents
One of Pollman's latest patents is titled "Method and apparatus for testing circuits containing active devices." This invention describes a test system that utilizes a pulsed bias technique to measure the characteristics of active circuits. The system periodically biases the input control port of the active circuit into its operational region, employing a pulsed RF source that is synchronized with the pulsed bias voltage. This method allows for efficient measurement of amplified RF power at the output port after separating it from the DC bias.
Another significant patent is the "High efficiency harmonic injection power amplifier." This invention features a power amplifier circuit paired with a second-harmonic termination circuit. The circuit samples a portion of the input signal and injects an amplified, phase-shifted harmonic signal into the power output. This design enhances the efficiency of the power amplifier by properly terminating harmonics, which can include additional circuits for higher-order harmonics.
