US Patent:

7884596, Feb 8, 2011

Filed:

Sep 26, 2007

Appl. No.:

12/443119

Inventors:

Richard R. Hawkins - Santa Rosa CA, US
Jon R. Sigler - Santa Rosa CA, US

Assignee:

Ladybug Technologies, LLC - Santa Rosa CA

International Classification:

G01R 17/02

US Classification:

324 98, 324706, 324725

Abstract:

A self-balancing Wheatstone bridge that provides frequency and power information. The frequency information obtained can be applied to correct the power measurement to provide excellent match, excellent frequency insensitivity, good dynamic range, good frequency range, and adequate frequency accuracy. The system is highly responsive, simple, and cost effective.

Appl. No.:

12/553066

Inventors:

Richard R. Hawkins - Santa Rosa CA, US
Jon R. Sigler - Santa Rosa CA, US

Assignee:

Ladybug Technologies, LLC - Santa Rosa CA

International Classification:

G01R 1/02

US Classification:

324130, 324105

Abstract:

An improved power sensor having an input connector connected to an input port having a center pin and a ground side; an amplifier; first and second detectors; and a thermal stabilization system, including a thermal mass disposed between the ground side of the input connection and the detectors, a ground plane for holding the temperature of thermally sensitive components constant to within 2 degrees C. , and a thermal impedance disposed between the center pin of the input port, preferably including a splitter and at least one DC capacitor, and a temperature sensor disposed on the ground plane.
