Abstract

This article presents the design and development of a balanced low noise amplifier suitable for WiMAX base station applications. The balanced low noise amplifier employs a compact 3 dB branch line coupler and advanced GaAs E-PHEMT technology to realize excellent return loss, noise figure and linearity performance as well as compact size. By using the compact branch line coupler, a size reduction of 40 percent is achieved as compared to using the conventional branch line coupler. The balanced LNA, using a compact branch line coupler designed on a printed circuit board PCB with Rogers 4003C substrate, exhibits a small-signal gain of 14.30 dB at 2.3 GHz and 13.50 dB at 2.7 GHz, a noise figure less than 1 dB, an OIP3 of 37.2 dBm and a P1dB of 21.28 dBm at 2.5 GHz.
