• Ensures high isolation between frequency bands to prevent cross-talk and maintain signal integrity in dual-band systems.
• Utilizes multilayer ceramic construction for reliable performance in surface-mount PCB layouts.

RF Multiplexers Applications

• Dual-band Wi-Fi access points and client devices
• Bluetooth-enabled wireless communication modules
• Smartphone and mobile device antenna sharing circuits

RF Multiplexers Procurement Notes

Verify the specific suffix A2 against the official datasheet to confirm electrical tolerances and pin configuration. Ensure the procurement channel provides original manufacturer documentation. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into production workflows.

RF Multiplexers Selection Notes

Select this component when designing for 2.4/5 GHz coexistence in minimal footprint scenarios. The 0402 package suits high-density boards where larger filters are impractical. Validate that the 50 Ohm system impedance matches the surrounding RF chain components to ensure optimal power transfer and return loss characteristics.

RF Multiplexers Part Context

This device belongs to the TDK DPX series of RF diplexers, which are engineered for wireless connectivity solutions.
