Abstract
A transmit block up-converter is provided for processing a multiplexed signal including a transmit IF signal, a reference frequency signal, a switching signal, a level signal and a constant-current signal, which is provided through one transmitting line from an indoor unit in the very small aperture terminal remote station for satellite communication. The transmit block up-converter includes a demultiplexer for demultiplexing the multiplexed signal; a frequency up-converter for frequency up-converting the transmit IF signal from the demultiplexer in response to the reference frequency signal, switching signal and level signal; an amplifier for amplifying the output signal from the demultiplexer; and an impedance matching circuit for impedance matching and amplifying an IF signal received from an external unit, and for outputting the impedance matched and amplified signal through one receiving line.
