发明名称 Amplification system for teledistribution.
摘要 <p>The system is modular; the main amplifier is connected to two rows (FIL1, FIL2,... and FIL4, FIL5,...) of UHF modules; each row consists of two 75 ohm lines (L1, L2 and L3, L4) having selective couplings; these lines ensure the passage of a continuous component, superimposed on the UHF signals, to supply the amplification modules PREAMP and/or the frequency-conversion modules CONV. &lt;IMAGE&gt;</p>
