The TDK Group has recently introduced a new LTE EPCOS (EPCOS) 1 duplexer, designed to offer exceptional performance in separating transmit and receive signals. This innovative component boasts an impressive isolation of up to 60 dB between the two channels, ensuring minimal interference and improved signal quality. The B8651 duplexer is built using SAW (Surface Acoustic Wave) technology, making it highly compact with a package size of just 1.8 mm x 1.4 mm.
One of the key advantages of this new duplexer is its ability to work seamlessly with envelope detectors, eliminating the need for additional pre-filters and power amplifiers. This not only simplifies the front-end design but also reduces overall system costs significantly. Additionally, the duplexer features a low insertion loss—only 1.9 dB in the transmit band—which helps conserve power and extend battery life in portable devices.
This advanced component is ideal for use in a wide range of LTE-enabled devices, including smartphones, tablets, and USB modems. Its combination of high isolation, low loss, and compact size makes it a valuable addition to modern wireless communication systems.

**Key Features:**
- Up to 60 dB isolation between transmit and receive channels
- Low insertion loss of 1.9 dB in the transmit band
- Compact SAW-based design (1.8 mm x 1.4 mm)
- Compatible with envelope detection power amplifiers
- Ideal for LTE USB devices, smartphones, and tablets
Whether you're designing next-generation mobile devices or looking to optimize existing systems, the new EPCOS B8651 duplexer offers a powerful and efficient solution that can help you stay ahead in the competitive world of wireless communications.
