Abstract :
This paper presents a high performance filter for wireless LAN applications in mobile phones. Excellent out-of- band attenuation performance in combination with low insertion loss is achieved by a combination of a SAW filter with high attenuation close to passband with a simple low-loss LTCC filter. The achieved performance makes it possible to use such filter in highly-integrated WLAN front-end modules.
