Abstract

When increasing a range of radar with an active phased antenna array (APAA) it is needed to generate pulses of increased power. To solve this problem, we use the multi-channel power amplifiers (MCPA) with extreme power levels under certain restrictions. Their practical implementation in radar is determined by an appropriate selection of efficient power supply and heat dissipation of the output transistors. From a variety of component units and products, as well as from constructive and technological solutions of their use, a developer has to implement an option optimally meeting a set of technical requirements. The issues of optimal solution are considered on an example of the L-band MCPA.
