D4I0810S-1

RF Circulators And Isolators Overview

The D4I0810S-1 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 800 MHz to 1 GHz frequency range. It features SMA-Female connectors and a module package with SMA connector configuration. Key electrical specifications include a maximum average forward power of 250 W, isolation of 40 dB, insertion loss of 0.8 dB, and a VSWR of 1.25. The component operates between -20°C and +65°C, complies with RoHS3 standards, and has an MSL rating of 1.

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 250 W for robust RF applications.
• Features low insertion loss of 0.8 dB to minimize signal attenuation in the transmission path.

RF Circulators And Isolators Applications

• High-power RF signal transmission systems
• Protecting amplifiers and oscillators from load mismatches
• Microwave communication equipment operating in the UHF band

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender and package dimensions against official datasheets before integration. Confirm RoHS3 compliance status and manufacturing origin if required by project specifications. Check current availability as lead times may vary. Ensure thermal management aligns with the specified operating temperature range of -20°C to +65°C during system design.

RF Circulators And Isolators Selection Notes

Select this model when a wideband isolator is needed for frequencies between 800 MHz and 1 GHz. The 250 W power rating makes it suitable for high-power transmitter chains. The SMA-Female interface simplifies integration into standard test and measurement setups. Consider the 40 dB isolation level for adequate protection against reflected power in sensitive RF circuits.

RF Circulators And Isolators Part Context

This component belongs to the D4I0810 series of RF isolators from DiTom Microwave. It shares similar frequency and power characteristics with other variants in the family but differs in connector configuration and packaging. The D4I0810S-1 specifically denotes the SMA-Female connector version, distinguishing it from male connector alternatives like the D4I0810N-1.
