Abstract
This paper presents an approach to design high directivity couplers on compact multilayer power amplifier module (PAM). Coplanar and bilevel coupled lines structures are analyzed and compared. The effects of layout are investigated. A bilevel coupled line coupler is developed and integrated into 700MHz UMTS 3×3mm2 PAM. It achieves more than 28dB directivity and the coupling factor variation of PAM is within ±0.15dB under VSWR 2.5∶1.
