摘要：
Four-port miniaturized 90 degree couplers composed of lumped elements have been developed. These couplers are realized below 500 MHz with reasonable dimensions of 12. 2 mm multiplied by 12. 2 mm multiplied by 7. 5 mm high. They can be used to build a number of devices, including phase shifters, image rejection mixers and many others.
