Abstract

In this paper, the Noise figure optimization circuit configuration in PHEMT Hybrid LNA design. The optimal noise ?gure is achieved by minimizing the noise contributions by utilizing of LC resonance at input and output matching networks to maintain transistor noise optimization. Design includes 2 stage cascaded common source PHEMT transistors with inter stage capacitor matching for improvement of gain. An LNA with Bandwidth 2. 3-5. 8GHz simulation in AWR Microwave office software shows forward gain of 24 dB, noise figure (NF) less than 2 dB and designed amplifier will give the best performance at 5GHz with NF of 0. 9 dB and with flat Gain of 24dB.
