ABSTRACT:
A paralleled amplifier arrangement includes a plurality of amplifier modules, the output ports of which are coupled to a common combining node. Switches are coupled to the output ports for selectively decoupling one or more of the amplifier modules from the combining node during those intervals in which the amplifier modules are held in reserve or are nonfunctional. Each amplifier module is associated with an isolation resistor which is coupled to all the isolation resistors. In order to reduce losses attributable to the isolation resistors when the decoupling switches are operated, the isolation resistors are each coupled to a switched network which decouples the isolation resistors associated with the decoupled amplifier modules.
