Abstract:
Structure and design methods of electrical power amplifiers suitable for broadband application such as television frequency or white spaces. An example broadband power amplifier passes a transmit carrier with modulations from BPSK to 256 QAM, on channel bandwidths from 6 to 32 MHz, over the entire UHF television band from 470 to 800 MHz using a low voltage, low power, narrowband power amplifier transistor. Based on a push-pull technique to lower the impedance level thus improving the match and doubling the power, the wide-band power amplification is performed with a balanced polynomial filter transform structure wherein the circuit impedance increases sequentially within the filter stage. The polynomial filtering makes high selectivity of out-of-band signals thereby cleaning up harmonic signals which prevent the need for additional high selective radio frequency filters. The invented power amplifier enables efficient broadband power amplifiers having a form factor within 300 square millimeters of space.

Claim (Index 1):
An electronic circuit comprising:\n a single-ended input port; an input transformer; an output transformer; a single-ended output port; and two single-ended amplifier legs connected from the input transformer to the output transformer, each related to a local DC power source and a local ground, both single-ended amplifier legs consisting, in order from input to output, of a first passive band-pass filter, a power amplifier, and a second passive band-pass filter, and wherein the first passive band-pass filter consists of, in order from input to output, of a series of stages where the stages are composed by a shunt capacitor to the local ground and an inductor in series, wherein each component value of each stages may be expressed as a polynomial.
