D3C9521S-5

RF Circulators And Isolators Overview

The D3C9521S-5 is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 2.15 GHz frequency range. It features SMA connectors with a Male-Female-Male configuration and supports a power rating of 75 W. Key electrical specifications include an insertion loss of 1 dB, isolation of 12 dB, and a VSWR of 1.65:1. The unit utilizes gold-plated brass contacts with a nickel-plated body, operating between +10°C and +55°C.

RF Circulators And Isolators Feature Summary

• Provides directional signal routing across a wide microwave frequency band
• Utilizes robust brass construction with gold-plated contacts for durability
• Supports high average forward power handling in a compact module format

RF Circulators And Isolators Applications

• Transmitter-receiver isolation in communication systems
• Antenna duplexer applications
• Test and measurement instrumentation setups

RF Circulators And Isolators Procurement Notes

Verify connector gender sequence (Male-Female-Male) against schematic requirements. Confirm SMA interface compatibility with mating cables. Ensure thermal management aligns with the specified operating temperature range of +10°C to +55°C. Check RoHS compliance status via official documentation before integration.

RF Circulators And Isolators Selection Notes

Select this model when a three-port circulator is required for the 950 MHz to 2.15 GHz spectrum. Consider the 75 W power rating and 12 dB isolation level for system performance needs. The SMA connector type dictates cable selection. Evaluate physical dimensions (2.8 x 1 x 2.8 inches) for enclosure fit.

RF Circulators And Isolators Part Context

This component belongs to the D3C9521S series of RF circulators from DiTom Microwave. It shares core electrical characteristics with variants like the D3C9521N-5 but differs in connector type, utilizing SMA instead of Type-N. The series targets general-purpose microwave applications requiring reliable signal directionality.

RF Circulators And Isolators Replacement Considerations

The D3C9521N-5 serves as a functional substitute with identical electrical parameters but uses Type-N Female connectors instead of SMA. Verify mechanical interface compatibility before substitution.
