Multiple Signal Intermodulation Reduction System

View page
US Patent:
7256649, Aug 14, 2007
Filed:
Feb 15, 2005
Appl. No.:
11/057979
Inventors:
David A. Ksienski - Los Angeles CA, US
Keven S. MacGowan - Rancho Palos Verdes CA, US
Samuel S. Osofsky - Rancho Palos Verdes CA, US
Albert M. Young - Whittier CA, US
Thomas T. Tam - Huntington Beach CA, US
Assignee:
The Aerospace Corporation - El Segundo CA
International Classification:
H03F 3/68
H04L 25/49
US Classification:
330124R, 375296
Abstract:
An intermodulation product reduction or cancellation amplifier received two input signals that are split in quadrature wherein the inphase outputs are summed and then amplified as an inphase signal, and the quadrature outputs are fixed-phase phase-shifted, then summed and then amplified as a quadrature signal. The inphase and quadrature signals are fed into an output hybrid for canceling intermodulation products, where the fixed-phase phase shift is +/−60 for reducing 3rd order, +/−36 for reducing 5th order, and +/−25. 71 for reducing 7th order intermodulation products, for examples, for improved signal communications of the two signals over a common antenna or link.

Higher-Order Intermodulation Reduction Using Phase And Angle Smearing

View page
US Patent:
7420508, Sep 2, 2008
Filed:
Feb 14, 2006
Appl. No.:
11/354551
Inventors:
David A. Ksienski - Los Angeles CA, US
James P. McKay - Hermosa Beach CA, US
Samuel S. Osofsky - Rancho Palos Verdes CA, US
Keven S. MacGowan - Rancho Palos Verdes CA, US
Gwendolyn M. Shaw - Torrance CA, US
Assignee:
The Aerospace Corporation - El Segundo CA
International Classification:
H01Q 3/00
US Classification:
342372, 342373
Abstract:
A method for reducing intermodulation beams includes applying a beam-smearing phase distribution in addition to a beam-steering distribution for scanning to an array of antenna elements such that multiple higher-order intermodulation products are simultaneously reduced.

Hybrid Active Combiner And Circulator

View page
US Patent:
20060087376, Apr 27, 2006
Filed:
Oct 25, 2004
Appl. No.:
10/973361
Inventors:
Albert Young - Whittier CA, US
Samuel Osofsky - Rancho Palos Verdes CA, US
Keven MacGowan - Rancho Palos Verdes CA, US
David Ksienski - Los Angeles CA, US
International Classification:
H03F 3/60
US Classification:
330286000
Abstract:
The hybrid active combiner and circulators serves as a coupler and is a three port network that integrates a directional coupler topology with active devices placed in the coupling paths in order to synthesize a low-loss active combiner circuit or a circulator device with minimal insertion losses. The coupler can have multiple stage amplifiers with transconductance values set according the Pascal's triangle for improved performance, and can function as a low cost and low weight transceiver well suited for various communications systems.
