The TDK Group has recently introduced a new LTE EPCOS (EPCOS) duplexer, the B8651 model, designed to enhance performance in communication devices. This advanced component features an impressive isolation of up to 60 dB between transmit and receive channels, ensuring excellent signal separation and reducing interference. Built on SAW (Surface Acoustic Wave) technology, the B8651 is compact, measuring just 1.8 mm x 1.4 mm, making it ideal for space-constrained applications.
One of the key advantages of this duplexer is its ability to work seamlessly with an envelope detector, eliminating the need for an additional power amplifier and pre-filtering. This simplifies the front-end design, significantly cutting down costs and improving system efficiency. Additionally, the B8651 offers a low insertion loss of only 1.9 dB in the transmit channel, which helps save power and extend battery life—critical factors for mobile and portable devices.
This component is primarily used in LTE-enabled USB devices such as smartphones, tablets, and laptops, where high performance and energy efficiency are essential. The B8651’s combination of small size, high isolation, and low loss makes it a valuable addition to modern wireless communication systems.
**Key Features:**
- Excellent isolation performance (up to 60 dB)
- Low insertion loss (1.9 dB in transmit band)
- Small package size (1.8 mm x 1.4 mm)
- Compatible with envelope detectors without extra filters
- Ideal for LTE USB devices, smartphones, and tablets
Whether you're designing next-generation mobile devices or optimizing existing systems, the B8651 duplexer from EPCOS offers a reliable and efficient solution for high-performance wireless communication.
