Abstract:

The paper assesses the integral energy characteristics of a receive-transmit module (RTM) operating in a pulsed mode, taking into account its construction scheme, characteristics of active and passive nodes, and proposes a formula that determines the dependence of the efficiency of the RTM on the efficiency of the transistor of output and the pre-output power amplifiers of microwave channel and of the ratio of duty cycle. The results of measurements of S-band RTM energy characteristics, carried out in the process of technological preparation of serial production of S-band RTM batch, are presented.

The integral energy characteristics of a receive-transmit module operating in a pulsed mode are assessed taking into account the construction scheme, characteristics of active and passive nodes. A formula is proposed that determines the dependence of the efficiency of the RTM on the efficiency of the transistor of the output and pre-output power amplifiers of the microwave channel and of the ratio of duty cycle. The results of measurements of S-band RTM energy characteristics, carried out in the process of technological preparation of serial production of S-band RTM batch, are presented.
