HIGH FREQUENCY MODULE AND ANTENNA DEVICE

Document Type and Number:

WIPO Patent Application WO/2003/081713

Kind Code:

A1

Abstract:

A high frequency module includes a first main waveguide (1), a T-shaped branching circuit (3) connected to the first main waveguide (1), a first low-pass filter (5) connected to the T-shaped branching circuit (3), a band-pass filter (7) connected to the first T-shaped branching circuit (3), a first converter (8) connected to the first low-pass filter (5) for converting the transmission path between the waveguide and a microwave integrating circuit, an amplifier (10) connected to the first converter and composed of a microwave integrating circuit, a second converter (9) connected to the amplifier (10) for converting the transmission path between the waveguide and the microwave integrating circuit, a second low-pass filter (6) connected to the second converter (9), a second T-shaped branching circuit (4) connected to the second low-pass filter and the band-pass filter (7), and a second main waveguide (2) connected to the second T-shaped branching circuit.
