Abstract
The invention relates to a broadband microwave device with switchable gain comprising a microwave signal input E and output S, a distributed amplifier with a plurality of amplifying cells comprising an input transmission line for an input signal applied to the microwave signal input E, said input transmission line having one of its two ends linked to the microwave signal input E, an output transmission line for said amplified input signal having an output end of the distributed amplifier, the cells of the distributed amplifier settable either to an amplifying state or to a blocked state. A switch switches the microwave signal output S either to a non-amplification position linked to the other end of the input transmission line, or to an amplification position linked to the output end of the distributed amplifier. A control unit supplies switch position control and amplifying cell status control signals.
