A Miniature Lumped-element LTCC Bandpass Filter with Finite Transmission Zeros for Bluetooth Applications

A compact, lumped-element bandpass filter with two finite transmission zeros, using a LTCC technique, is proposed for Bluetooth applications. Based on the traditional second-order bandpass filter, a feedback capacitor is added in the middle of the coup...
Bluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. A Bluetooth device, as well as a cell phone, is often carried by people themselves, resulting in a very compact size requirement for the Bluetooth...
