US Patent:

7890067, Feb 15, 2011

Filed:

May 10, 2007

Appl. No.:

11/801444

Inventors:

John R. Lane - Forest VA, US
William P. Overstreet - Lynchburg VA, US

Assignee:

Pine Valley Investments, Inc. - Las Vegas NV

International Classification:

H04B 1/04

US Classification:

455126, 4551272

Abstract:

A system for power amplification of an RF signal including polar feedback control. The system may include a feedback-controlled modulator configured to modulate an RF signal based on a feedback-corrected control signal. The modulator is further configured to generate a modulated RF signal. The system also may include a phase shifter configured to correct the phase of the modulated RF signal based on a feedback phase control signal. The system further includes a power amplifier in communication with the modulator and/or the phase shifter. The amplifier is configured to amplify the modulated RF signal and to generate an amplified RF output signal. The system also includes a feedback network configured to generate polar feedback signals, including the feedback-corrected control signal and/or the feedback phase control signal.

Abstract:

An architecture and frequency plan for a wideband UHF radio minimizing spurious output signal emissions uses a low value for the ratio of the maximum RF operating frequency to the (first) intermediate frequency (IF) in the radio, as part of its internal superheterodyne conversion process. A minimum value or a value sufficiently close to the minimum value of this ratio allows the radio design to be optimized to reduce spurious outputs and the effects of inherently present major harmonics. These and other advantages and features permit a radio design to be realized in a cost effective manner for an array of stringent performance specifications including low spurious output emissions.
