Claims
- 1. A wide-band RF signal power sensor, comprising:
a waveguide connector for guiding a signal propagating in a waveguide to a power sensor; a module casing including a waveguide type hollow portion; a fin line module substrate formed in a portion of said hollow portion of said module casing; a power sensor element formed on said fin line module substrate; and a lead line for guiding an output signal from said power sensor element to a dedicated meter.
- 2. A sensor according to claim 1, wherein said fin line module substrate is set parallel to a longitudinal direction of said waveguide-shaped hollow portion.
- 3. A sensor according to claim 1, wherein said fin line module substrate is set parallel to the longitudinal direction of said waveguide-shaped hollow portion and perpendicular to a longitudinal direction of a section of said waveguide-shaped hollow portion.
- 4. A sensor according to claim 1, wherein said fin line module substrate is set parallel to the longitudinal direction of said waveguide-shaped hollow portion and perpendicular to a longitudinal direction of a section of said waveguide-shaped hollow portion, and is placed in ⅓ portions from centers in the longitudinal directions.
- 5. A sensor according to claim 1, wherein said module casing is constructed of complementary separate casings.
- 6. A sensor according to claim 1, wherein said fin line module substrate has a recess by which absolute values of reflection produced in said power sensor element and reflection produced in said fin line module substrate are substantially equal to each other, and a phase difference therebetween is substantially 180°.
- 7. A sensor according to claim 5 wherein said module casing, which is constructed of complementary separate casings, has a signal input terminal and sensor output terminals formed in a front portion and a rear portion thereof, and a calibration signal input terminal formed on one side thereof.
