摘要: A small size, low cost balun is formed on a substrate, such as gallium arsenide, an integrated passive device. Multiple baluns are same allowing multi-band operation. For example, symmetrical transformers provided for two different bands of operation, quad-band GSM application. Each the used frequency operation ground ring allows Hi-Q to be circuit side-by-side with minimum spacing and impact phase amplitude performance over By using multiple substrate or chip, size may reduced.
