A design technique for LNA size miniaturisation is described which does not compromise electrical performance. The method has been applied to the design of an L-hand LNA and results in a measured noise figure of 0.25dB and 15dB associated gain. The circuit is realised in MIC technology with a total surface area of less than 4.8 x 8.8mm2.The reduced size allows the LNA to be cascaded mth MMIC gain blocks with little or no volume impact and considerably improved electrical performance compared with a complete MMIC solution.
