Voltage Controlled Attenuator With No Intermodulation Distortion

US Patent:
7256664, Aug 14, 2007
Filed:
Apr 15, 2005
Appl. No.:
11/107586
Inventors:
Robert J. Blacka - Pennsauken NJ, US
Nelson Roldan - Boca Raton FL, US
Assignee:
Smiths Interconnect Microwave Components, Inc. - Stuart FL
International Classification:
H01P 1/22
US Classification:
333 81R
Abstract:
A preferred embodiment of the present invention comprises at least first and second thermistors, arranged into a classical Tee, Pi, or Bridged Tee attenuator design, a heating element, a temperature sensor, and a control circuit. The thermistors have different temperature coefficients of resistance and are in close proximity to the heating element and the temperature sensor. The control circuit receives a voltage signal from the temperature sensor, compares that signal with a voltage signal specifying a desired temperature, and applies electrical energy to the heating element until receiving a signal from the temperature sensor that the temperature of the thermistors matches the desired temperature. As a result, the attenuation of the attenuator can be changed at a controlled rate by varying the temperature of the thermistors, while the impedance of the attenuator remains within acceptable levels.
