The variations in varactor parameters which can be compensated by the electrical re‐tuning of two specific amplifiers have been studied using a digital computer. The designs of two different microstrip parametric amplifiers were at first optimized with respect to the bandwidth. Then after changing the varactor parameters, pumping and biasing conditions were optimized in order to attain maximum flat gain bandwidth within certain acceptable limits for gain and frequency. The results show that considerable variations can be compensated electrically.
