摘要: At frequencies below 18 GHz, distributed element hybrids consume too much valuable GaAs real estate to be cost-effective. An appreciable reduction in surface area without a degradation electrical performance can realized with the use of lumped hybrids. This paper describes design methodology employed development 180-degree hybrid. technique is also applicable other devices such as 90-degree branch line hybrid and Wilkinson power divider.
