Filed:

Jul 21, 2000

Appl. No.:

09/621191

Inventors:

Roy E. Mallory - Bedford MA
Richard B. Carter - Marlborough MA

Assignee:

ADE Corporation - Westwood MA

International Classification:

G01R 2726

US Classification:

324688, D10 80

Abstract:

A capacitive displacement sensor for measuring thin targets is presented.

International Classification:

H01P 1/15
H01P 1/18

US Classification:

333104, 333161

Abstract:

According to one exemplary embodiment, a switching device with phase selection terminals to select between at least two phase shifting modes to reduce intermodulation distortion in the switching device includes a first phase selection terminal to select a first phase shifting mode of the switching device by enabling a first transmission line in a first phase shifting switching branch coupled to an input of the switching device. The switching device further includes a second phase selection terminal to select a second phase shifting mode of the switching device by enabling a second phase shifting switching branch coupled to the switching device input. The intermodulation distortion in the switching device is reduced by selecting one of the first and second phase shifting modes. The first transmission line is enabled by enabling a FET coupled in series with the first transmission line in the first phase shifting switching branch.

US Classification:

333103, 333 32, 333175

Abstract:

According to one exemplary embodiment, a switching module includes a first harmonic phase tuning filter coupled to a first input of an RF switch. The first harmonic phase tuning filter is configured to provide an output impedance that substantially matches an input impedance of the RF switch at approximately a fundamental frequency and to provide a low impedance at approximately a harmonic frequency generated by the RF switch. The first harmonic phase tuning filter includes an LC circuit coupled between an output terminal of the first harmonic phase tuning filter and a ground and tuned to provide the low impedance at approximately the harmonic frequency generated by the RF switch. The RF switching module further includes a second harmonic phase tuning filter coupled to a second input of the RF switch. The first and second harmonic phase tuning filters can be fabricated on a single semiconductor die.
