Abstract
본 발명은 무선신호를 수신하는 안테나의 제어에 관한 것으로, 특히 위상 동기 루프(PLL) 제어전압으로 안테나 수신 주파수를 제어하여 수신대역폭이 좁은 안테나로도 광대역의 신호를 수신토록 한 안테나 수신주파수 제어장치에 관한 것이다.The present invention relates to the control of an antenna for receiving a radio signal. In particular, an antenna reception frequency control apparatus for controlling an antenna reception frequency with a phase locked loop (PLL) control voltage to receive a wideband signal even with an antenna having a narrow reception bandwidth. It is about.
이러한 본 발명은 안테나의 수신주파수 조절 및 발진 주파수 조절을 위한 제어전압을 출력하는 위상 동기 루프부와, 위상 동기 루프부에서 출력되는 제어전압을 필터링하여 출력하는 루프 필터부와, 루프 필터부에서 출력되는 제어전압에 따라 수신 주파수 대역을 조절하여 수신하는 바랙터 다이오드와, 수신기로 이루어진 안테나부로 이루어진다.The present invention is a phase-locked loop unit for outputting a control voltage for adjusting the reception frequency and oscillation frequency of the antenna, a loop filter unit for filtering and outputting the control voltage output from the phase-locked loop unit, and output from the loop filter unit The antenna unit includes a varactor diode configured to receive and adjust a reception frequency band according to a control voltage.
