| 摘要 |
The invention relates to a high-frequency amplifier unit replicated on the hot standby principle, comprising switching means (S1, S2) for connecting a signal to be amplified through two alternative amplifier branches (LNA1, LNA2). The amplifier unit of the invention is of modular structure in such way that the two amplifier branches (LNA1, LNA2) are positioned in their own separate structural modules (6, 7) detachable from the amplifier unit without breaking the signal path passing through the structural module containing the other amplifier branch. |
