Custom Multiplexer / Diplexer Engineering

Modifications & Mission Critical Packaging

Modifications & Mission-Critical

RF Components specializes in custom Multiplexers and Diplexers, engineered to meet the stringent requirements of commercial, military, and aerospace systems. With decades of RF and microwave engineering experience, we deliver high-performance, reliable solutions tailored to your exact frequency and system specifications.

Extreme Temperature

Our Multiplexers/Diplexers are designed for extreme operating environments, including cryogenic scientific research and high-temperature aerospace systems. These devices provide stable frequency separation, high isolation, and long-term reliability, even where standard multiplexers or diplexers fail.

Form Factor

Custom form-factor solutions include hermetically sealed packages, optimized connector placement, and high-density SMT layouts, engineered to meet tight SWaP (Size, Weight, and Power) constraints without compromising electrical or mechanical performance. Ideal for space-constrained RF systems.

Choosing the Right Multiplexer / Diplexer

When selecting a Multiplexer or Diplexer for your RF system, consider the following:
Frequency Bands: Ensure the device supports all frequency bands in your system. Isolation Requirements: High isolation is critical to prevent interference between channels. Insertion Loss: Choose devices with low insertion loss to maintain signal strength. Port Configuration: Determine how many input/output ports are required for your application. Power Handling: Verify the device can safely handle your system’s signal power. Size Constraints: Consider SWaP requirements for aerospace, military, or compact installations. Our engineering team can guide you in selecting or designing a custom solution to meet your exact operational needs.

Technical FAQ

What is the difference between a multiplexer and a diplexer?
A Multiplexer (Mux) combines multiple frequency bands into a single output. A Diplexer separates signals into two or more frequency bands while sharing a common port.
Yes. Our Multiplexers/Diplexers are optimized for high-frequency RF systems, including 5G, Satcom, and radar.
Isolation depends on your system requirements. We can provide custom designs to achieve high channel separation and minimize interference.
