A diplexer is a specific type of multiplexer that combines or separates two frequency bands. A general multiplexer can handle three or more bands, often referred to as triplexers or quadplexers.

What are RF Multiplexers & Diplexers components?
RF multiplexers, including diplexers and triplexers, are passive components used to route multiple frequency signals through a single antenna or transmission line. They are critical for multi-band wireless systems, requiring careful matching of insertion loss and isolation.
How to Choose RF Multiplexers & Diplexers Components
Selecting the right multiplexer requires balancing signal integrity with physical space constraints.
Frequency Band Alignment
Ensure the passbands align exactly with your system's operating frequencies to avoid signal attenuation.
Insertion Loss
Minimize insertion loss to preserve signal power, especially in battery-operated or long-range RF applications.
Isolation Requirements
High port-to-port isolation is mandatory to prevent cross-talk between transmit and receive paths.
Power Handling
Verify the component's maximum power rating matches your transmitter's output to prevent thermal failure.
Package Footprint
Consider SMD size constraints; smaller packages often trade off performance for board density.
