Microwave integrated circuit (IC) design tends to become more efficient and less expensive which leads to emerging the circuit topology and layout synthesis software. In the paper we present a technique and an algorithm for microwave distributed amplifier (DA) automated synthesis based on requirements to linear characteristics. The technique feature is the using of active and passive element’s models for a chosen IC process. This allow the technique to generate circuit topology which can be manufactured using a given IC process. The proposed DA automated design technique work was demonstrated with preamplifier stage design for 20–30 GHz buffer amplifier MMIC based on the 0.25um GaAs pHEMT process of Svetlana-Rost foundry in Saint-Petersburg.
