摘要: 【課題】周波数特性を改善した周波数混合器を提供する。 【解決手段】周波数混合器は、IF信号を濾波するIF信号フィルタ101と、局部発振器から入力されるLO信号を濾波するLO信号フィルタ104と、IF信号及びLO信号を混合してRF信号を生成するλ/2バラン100、第1、第2ダイオード108、110、短絡回路109、111を備える。LO信号フィルタとλ/2バラン100との間のLO伝送線路105には、IF信号フィルタ101と同じ周波数帯域の濾波を行うフィルタ106を介して終端器107が設けられる。フィルタ106及び終端器107は、λ/2バラン100からLO信号フィルタ104に入力されるIF信号を吸収することで、反射したIF信号がλ/2バラン100に入力されることを防止して、リップルの発生を抑制する。リップルの発生を抑制することで周波数混合器の周波数特性が改善する。 【選択図】図1

摘要: PROBLEM TO BE SOLVED: To provide a resonator which is equipped with an input/output mechanism of an antenna system, which facilitates positioning of an antenna, and which dispenses with a screw for adjusting the degree of coupling. SOLUTION: A resonator, which is equipped with an input/output mechanism of an antenna system, propagates a high-frequency signal, and constitutes a filter device by being combined with a resonator in which only a resonance rod is disposed. The resonator comprises a coupling rod which is connected to a terminal for inputting or outputting the high-frequency signal and which is disposed in parallel with the resonance rod via an insulator in a cabinet, and a coupling line which is made of a metallic conductor, which has one end connected to the terminal and which has the other end fixedly connected to the coupling rod by means of a screw made of an insulator. The coupling rod is disposed via the insulator in the cabinet by means of the screw to function as an antenna, and electromagnetically coupled to the resonance rod. COPYRIGHT: (C)2012,JPO&INPIT

摘要: PROBLEM TO BE SOLVED: To prevent the occurrence of loss even when antennas of respective reception systems are installed separately from each other when synthesizing radio signals sent by a plurality of reception systems. SOLUTION: A signal processing part 300 of each reception system not only converts a received radio signal to digital data but also generates gain control data and performs such control by the gain control data that an average amplitude of the radio signal amplified by a radio part 200 is fixed, and outputs the gain control data together with the digital data. A digital synthesis circuit 400 captures data output from each signal processing part 300, through a digital transmission line and synthesizes the digital data and the gain control data out of the captured data into one. Digital data output from the digital synthesis circuit 400 are converted to a radio signal, and then its amplitude is controlled to a fixed gain on the basis of the gain control data output from the digital synthesis circuit 400.
