The EPCOS B39941-B8048-P810 is a high-performance duplexer utilizing a ceramic cavity filter architecture for LTE Band 8 (880–915MHz) applications. This device offers a maximum insertion loss of 1.8dB at the center frequency and provides isolation of 32dB or more under specified conditions.
Built with EPCOS' proprietary multi-layer LTCC technology, this duplexer achieves a Q factor exceeding 1200, significantly outperforming traditional SAW devices. Its -3dB bandwidth is 35MHz, with a -40dB stopband width extending to 120MHz, ensuring effective suppression of adjacent channel interference.
The 2520 (2.5x2.0mm) package is optimized for high PCB layout density, making it suitable for compact terminal designs. However, designers should consider its thermal resistance of 78K/W and potential frequency drift due to temperature variations, implementing thermal management strategies as needed.
This duplexer meets 3GPP TS 36.101 Class 3 standards and offers harmonic suppression greater than 65dBc, crucial for regulatory compliance such as FCC Part 22.913 or CE EN 300 220.
