Abstract

A LNA(Low Nosise Amplifer) module for the Ka-band satellite transponder has been developed, which is composed of developed two MMIC chips and 50$\Omega$ line. This LNA exhibited noise figure less than 3.12dB, linear gain higher than 32dB from 30.085GHz to 30.885GHz frequency range. Temperature test from $20^{\circ}to$ $60^{\circ}C$ of the LNA Module showed very small noise figure and linear gain variation of 0.2 dB and 0.4dB.
