Compact Filtering Solutions for Modern Wireless Designs

Modern wireless devices demand precise signal routing, minimal interference, and efficient use of PCB space. YAGEO Group’s DPX1608LKE5R2460A and DPX2012LRGYR2558A diplexers are engineered to meet these needs, offering compact, surface-mount solutions for dual-band Wi-Fi applications. The DPX1608LKE5R2460A supports 2.4 GHz, 5 GHz, and 7 GHz frequency bands for full Wi-Fi 6E/7 coverage, while the DPX2012LRGYR2558A is optimized for traditional 2.4 GHz and 5 GHz operation.

These LTCC-based diplexers eliminate the need for discrete filtering components—simplifying layout and streamlining the RF path in space-constrained environments like smartphones, wearables, modules, and IoT devices.
