Latest Patents
Keen's patent, titled "Method and apparatus for increasing the bandwidth, and reducing the," presents a novel method for optimizing RF circuitry. This invention utilizes a DC bias circuit to provide bias voltage to impedance-matched circuitry. A dielectric member with a high dielectric constant is strategically placed adjacent to the bias feed line, which connects the DC bias circuit to the remaining circuitry. This arrangement helps maintain high RF impedance while simultaneously reducing impedance at lower frequencies. The invention is particularly valuable for RF amplifiers, which are instrumental in amplifying modulated carriers, including video signals comprising an RF carrier and lower-frequency modulation. For effective performance, the bias feed line's physical length is selected to be a quarter of the wavelength of the RF carrier.
