與前向放大器相比，RF-Lambda雙向放大器的增益比前向放大器小，因?yàn)樯闲胁?span style="font-family:Calibri">(反向)通常是低頻信號(hào)，低頻波對(duì)電纜的衰減較小，因此與前向所需增益相比，下行電視信道的射頻信號(hào)被F座標(biāo)記為"RF IN"引入放大器。
RF-LAMBDA射頻信號(hào)是耦合C1一個(gè)高頻，高壓片式電容，前向放大器模塊由雙向?yàn)V波器（高頻通道），前向手動(dòng)衰減器，前向手動(dòng)均衡器和前向頻率響應(yīng)校正器進(jìn)入。放大后的射頻信號(hào)經(jīng)過"雙向?yàn)V波器"（高頻通道），橋式支路/分配器，高頻高壓瓷片電容C19，最后將放大器從F座"RF OUT"引至下一級(jí)或用戶。橋式支路/分配器分離出的另一射頻信號(hào)可根據(jù)用戶需要，通過C20，F座"RFBR"制成各種支路的橋式信號(hào)送出放大器。也可以衰減20 dB作為測試信號(hào)，為維護(hù)人員提供不間斷的測試，這個(gè)測試信號(hào)電平加上20 dB就是放大器RF OUT"端口的實(shí)際輸出電平。上行回傳信號(hào)由F 座RF OUT引入，經(jīng)過雙向?yàn)V波器（低頻通道），反向頻率響應(yīng)校正器，反向手動(dòng)衰減器，反向固定均衡器三個(gè)低通濾波器，進(jìn)入反向放大模塊。放大后的射頻信號(hào)為C1，經(jīng)雙向?yàn)V波器（低頻通道），高頻高壓陶瓷片電容，放大器最終從F座"RFIN"引出，到上層放大器或直接到光節(jié)點(diǎn)。
