A diplexer combines or separates signals based on frequency, while a duplexer is specifically designed to allow simultaneous transmit and receive on the same antenna, often using the same frequency band with different timing or polarization.
RF Multiplexers Component Intelligence
Optimize antenna sharing and signal routing in multi-band RF front-ends.
What are RF Multiplexers components?
RF multiplexers (diplexers, triplexers, quadplexers) are passive components used to combine or split signals across different frequency bands. They are essential for allowing multiple radios to share a single antenna while maintaining high isolation and low insertion loss.
How to Choose RF Multiplexers Components
Selecting the right multiplexer requires balancing signal integrity with physical space constraints.
Band Isolation
Ensure high isolation between ports to prevent cross-talk and interference between different frequency bands.
Insertion Loss
Minimize insertion loss to preserve signal power, especially critical in battery-operated or long-range RF systems.
Frequency Range
Verify the passband and stopband characteristics match your specific wireless protocol requirements (e.g., Wi-Fi, LTE, 5G).
Power Handling
Confirm the component can handle the peak transmit power of your system without thermal degradation.
Package Size
Consider SMD footprint and height constraints, particularly for compact mobile or IoT device layouts.
