D3I0112-3

RF Circulators And Isolators Overview

The D3I0112-3 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 1.2 GHz to 1.4 GHz frequency range. It features SMA-FEMALE connectors and utilizes a module format with SMA connections. The component supports an average forward power of 200 W and provides 20 dB of isolation. Key electrical specifications include an insertion loss of 0.4 dB and a VSWR of 1.25. The device operates within a temperature range of -20°C to +65°C and measures 2.5 in x 0.73 in x 1.25 in.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with 20 dB isolation to protect source components from reflected energy.
• Supports high average forward power handling up to 200 W for robust RF system integration.
• Features low insertion loss of 0.4 dB to minimize signal attenuation in the transmission path.

RF Circulators And Isolators Applications

• L-band wireless communication systems
• Microwave transmission links
• RF source protection in test and measurement equipment

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and mechanical dimensions against the official datasheet before integration. Confirm RoHS compliance status and environmental operating limits (-20°C to +65°C) match the target application requirements. Ensure the SMA-FEMALE interface aligns with existing system cabling and fixture designs to prevent mismatch issues.

RF Circulators And Isolators Selection Notes

Select this model when a 1.2–1.4 GHz frequency band is required with high power handling capabilities. The 200 W average power rating distinguishes it from lower-power alternatives suitable for similar bands. Consider the physical module size and SMA connector type for board layout and interconnect compatibility within the RF chain design constraints.

RF Circulators And Isolators Part Context

This component belongs to the D3I0112 series of single junction coaxial isolators produced by DiTom Microwave. The series spans the 1.2 to 1.4 GHz range, offering variations in connector types and configurations. The D3I0112-3 specifically denotes the SMA-FEMALE connector variant within this family, maintaining consistent core electrical performance characteristics across the series.

RF Circulators And Isolators Replacement Considerations

D3I0112-1: Same frequency range (1.2–1.4 GHz), power (200 W), and isolation (20 dB). Verify connector compatibility as suffixes may indicate different interface configurations or minor mechanical variations not explicitly detailed in general summaries.
