Description

technical field [0001] The invention relates to a high-frequency circuit, a low-noise block down-converter and an antenna device, in particular to a high-frequency circuit using a microstrip line, a low-noise block down-converter and an antenna device. Background technique [0002] LNB (Low Noise Block Down Converter: Low Noise Block Down Converter) is installed in the antenna called the outdoor unit of the two-way satellite transceiver system. The LNB receives the weak radio waves from the satellite, that is, the RF (Radio Frequency: Radio Frequency) signal through the antenna, performs low-noise amplification on the received RF signal, and converts it to an intermediate frequency (IF (Intermediate Frequency: Intermediate Frequency) frequency). The LNB then outputs an IF signal with low noise and sufficient level to the indoor unit. Using such an antenna and LNB, a user can receive a satellite broadcast service using a terminal such as a television set connected to an indo...
