Patent ID: 7019706

Claim:
A high frequency module, characterized by comprising: a first main waveguide; a first T-branch circuit connected to the first main waveguide; a first low-pass filter connected to the first T-branch circuit for transmitting a first frequency band and reflecting a second frequency band; a band-pass filter connected to the first T-branch circuit for transmitting the second frequency band and reflecting the first frequency band; a first converter connected to the first low-pass filter for converting transmission lines between a waveguide and a microwave integrated circuit; an amplifier connected to the first converter and structured by the microwave integrated circuit; a second converter connected to the amplifier for converting transmission lines between a waveguide and the microwave integrated circuit; a second low-pass filter connected to the second converter for transmitting the first frequency band and reflecting the second frequency band; a second T-branch circuit connected to the second low-pass filter and the band-pass filter; and a second main waveguide connected to the second T-branch circuit.
