D4I9525-1

RF Circulators And Isolators Overview

The D4I9525-1 is a single junction RF isolator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 1.225 GHz frequency range. It features SMA female connectors and supports an average forward power of 250 W. Key electrical specifications include 40 dB isolation, 0.8 dB insertion loss, and a VSWR of 1.25. The component operates between -20°C and +65°C, with physical dimensions of 2.5 in x 0.73 in x 1.25 in.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance of 40 dB to protect sensitive RF sources from reflected signals.
• Supports high average forward power handling up to 250 W for robust signal transmission.
• Features low insertion loss of 0.8 dB to minimize signal attenuation in the passband.

RF Circulators And Isolators Applications

• RF source protection in communication systems
• Signal integrity maintenance in microwave test equipment
• Isolation in radar transmitter chains

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender configuration against official documentation, as variations exist within the series. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure thermal management aligns with the specified operating temperature range during integration.

RF Circulators And Isolators Selection Notes

Select this model when unidirectional signal flow is required in the 950 MHz to 1.225 GHz band. Consider the 250 W power rating and 40 dB isolation level relative to system requirements. Compare physical dimensions and SMA female interface compatibility with existing circuit board layouts or waveguide transitions before finalizing the design.

RF Circulators And Isolators Part Context

This component belongs to the D4I9525 series of microwave isolators from DiTom Microwave. The series includes variants with different connector configurations and junction types, such as the D3I9525S. These components are categorized under RF circulators and isolators, serving critical roles in managing signal directionality in high-frequency electronic systems.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-model variants like D3I9525S only if connector gender differences (female-female vs male-female) are acceptable and electrical parameters remain within system tolerances.
