Abstract

In this work, a highly miniaturized amplifier MMIC (Monolithic Microwave Integrated Circuit) was developed for application to a marine disaster warning system. According to measured results, the proposed amplifier MMIC showed good RF characteristics in a wide frequency range. Concretely, the Proposed amplifier MMIC showed a gain of 20 ±2 dB between 17 GHz and 27 GHz. The measured P out was 17.79 dBm at 25 GHz. The measured P 1dB of the amplifier MMIC exhibited the value of 15±2.5 dBm between 17 GHz and 27 GHz.
