D4I0555-1

RF Circulators And Isolators Overview

The DiTom Microwave D4I0555-1 is an RF isolator designed for the 500 MHz to 550 MHz frequency range. It features SMA-FEMALE connectors and operates within a temperature range of -20°C to +65°C. The component supports an average forward power of 300 W with a maximum isolation of 40 dB. Key electrical specifications include an insertion loss of 0.8 dB and a Voltage Standing Wave Ratio (VSWR) of 1.25. The unit is housed in a module package measuring 3.16 inches by 0.73 inches by 1.62 inches.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance of 40 dB to protect source components from reflected signals.
• Supports high average forward power handling up to 300 W for robust operation.
• Features low insertion loss of 0.8 dB to minimize signal attenuation in the transmission path.

RF Circulators And Isolators Applications

• RF signal transmission systems requiring unidirectional flow
• Protection of microwave sources and amplifiers
• Test and measurement equipment setups

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and isolation rating against project requirements before ordering. Confirm that the operating frequency range aligns with system specifications. Check compliance with RoHS3 standards if environmental regulations apply. Ensure the physical dimensions fit within the designated enclosure space. Validate thermal management capabilities for the expected power levels.

RF Circulators And Isolators Selection Notes

Choose this model when high isolation is critical for system stability. Consider the 300 W power rating for high-power applications. Evaluate the SMA-FEMALE interface compatibility with existing cabling. Assess the need for the specific 500-550 MHz bandwidth. Compare insertion loss requirements against other available isolators.

RF Circulators And Isolators Part Context

This component belongs to the D4I0555 series of RF isolators manufactured by DiTom Microwave. The series offers various configurations with different isolation levels and connector types. The D4I0555-1 specifically denotes the variant with 40 dB isolation and SMA-FEMALE connectors. It is part of a broader portfolio of microwave passive components.

RF Circulators And Isolators Replacement Considerations

D4I0555 is a related part number within the same series, offering similar specifications but potentially differing in connector or isolation details. Verify exact parameter matching before substitution. Other models like D3I0555-1 offer lower isolation ratings and should only be considered if reduced performance is acceptable.
