Title:

WIDE-BAND HIGH-FREQUENCY SIGNAL POWER DETECTING ELEMENT AND POWER DETECTOR USING THE SAME

Document Type and Number:

WIPO Patent Application WO/1999/061926

Kind Code:

A1

Abstract:

A wide-band high-frequency signal power detecting element provided, on a substrate (21) having an insulating property, with at least one thin film resistor (22a) which generates heat upon absorbing the power of a signal to be measured, first and second grounding electrodes (27 and 28) respectively formed of thin film conductors, a first thin film connecting section (24) which electrically connects the first grounding electrode (27) to the resistor (22a), a second thin film connecting section (25) which electrically connects the second grounding electrode (28) to the thin film resistor (22a) and, at the same time, is formed so that the interval between the first and the second thin film connecting sections (24 and 25) may become narrower as going toward the resistor (22a), and an input electrode (26) which is arranged between the first and the second grounding electrodes (27 and 28) and electrically connected to the resistor (22a).
