Title (EN) RELAY TRANSMITTER APPARATUS
(FR) TRANSMETTEUR RELAIS
(JA) 中継送信装置
Abstract:
(EN) A relay transmitter apparatus wherein a single constituent part is used to process a plurality of digital modulated signals occupying different frequency bands. A frequency converter (16a) converts the frequency band of a signal received via a reception antenna (10) and a reception amplifier (14), and inputs the resultant signal to an analog input/output filter (18a). The analog input/output filter (18a) passes a digital modulated signal, while attenuating an analog modulated signal. The analog input/output filter (18a) inputs a band-limited signal to a frequency converter (22a). The frequency converter (22a) converts the frequency band of the input signal. The frequency-band-converted signal is then transmitted via a transmission amplifier (24), a transmission filter (26) and a transmission antenna (28).
(FR) La présente invention se rapporte à un transmetteur relais dans lequel un seul constituant sert à traiter une pluralité de signaux modulés numériques occupant différentes bandes de fréquence. Un convertisseur de fréquence (16a) convertit la bande de fréquence d'un signal reçu via une antenne de réception (10) et un amplificateur de réception (14) et envoie le signal en résultant vers un filtre d'entrée/sortie analogique (18a). Le filtre d'entrée/sortie analogique (18a) transmet un signal modulé numérique, tout en atténuant un signal modulé analogique. Le filtre d'entrée/sortie analogique (18a) envoie un signal à bande limitée à un convertisseur de fréquence (22a). Le convertisseur de fréquence (22a) convertit la bande de fréquence du signal d'entrée. Le signal à bande de fréquence convertie est alors transmis via un amplificateur de transmission (24), un filtre de transmission (26) et une antenne de transmission (28).
(JA)  互いに異なる周波数帯域を占有する複数のディジタル変調信号を、単一の構成部で処理する中継送信装置を提供する。周波数変換器16aは、受信アンテナ10および受信増幅器14を介して受信された信号の周波数帯域を変換し、アナログ入出力フィルタ18aに入力する。アナログ入出力フィルタ18aは、ディジタル変調信号を通過させアナログ変調信号を減衰させる。アナログ入出力フィルタ18aは帯域制限を施した信号を周波数変換器22aに入力する。周波数変換器22aは入力された信号の周波数帯域を変換する。周波数帯域が変換された信号は、送信増幅器24、送信フィルタ26、および送信アンテナ28を介して送信される。
