RDP-6500+

RF Multiplexers Overview

The RDP-6500+ is a lumped LC diplexer from Mini-Circuits designed for signal separation in RF systems. It features two distinct passbands: a lowpass port covering DC to 100 MHz and a highpass port spanning 1400 MHz to 6500 MHz. The component operates with a standard 50-ohm impedance system, ensuring compatibility with common RF infrastructure. Packaged in a compact CK605 surface-mount format, it provides efficient isolation between frequency bands. This configuration allows for the simultaneous handling of baseband control signals and high-frequency carrier waves within a single circuit path without interference.

RF Multiplexers Feature Summary

• Combines lowpass and highpass filtering functions into a single dual-port device
• Provides wideband coverage extending up to 6500 MHz for the highpass channel
• Utilizes lumped LC topology for compact surface-mount integration

RF Multiplexers Applications

• Separating baseband control signals from RF carrier frequencies
• Integrating low-frequency monitoring ports into high-frequency transmission lines
• Compact RF front-end modules requiring DC-to-microwave signal routing

RF Multiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and termination style. Confirm that the required frequency ranges align with the specified DC-100 MHz and 1400-6500 MHz passbands. Check for any recent revisions to the CK605 case dimensions or pinout configuration prior to finalizing design-in decisions.

RF Multiplexers Selection Notes

Select this component when a single device must handle both sub-100 MHz baseband and multi-Gigahertz RF signals. The lumped LC design offers a smaller footprint compared to distributed line alternatives. Ensure the application environment supports the thermal characteristics associated with SMD packages. Validate that the insertion loss and rejection specifications meet the system's noise floor requirements.

RF Multiplexers Part Context

This diplexer belongs to Mini-Circuits' range of passive RF components designed for signal conditioning. It complements other filters and multiplexers by providing a specialized solution for separating widely spaced frequency bands. The product line emphasizes compactness and reliability for modern electronic equipment where space constraints are critical.

RF Multiplexers Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that alternative parts match the DC-100 MHz and 1400-6500 MHz split points. Ensure equivalent impedance and package compatibility before substitution.
