DSI2731-3

RF Circulators And Isolators Overview

The DiTom Microwave DSI2731-3 is a waveguide RF isolator designed for the 27.00–31.00 GHz frequency range. It provides a minimum isolation of 20 dB and a maximum insertion loss of 0.6 dB. The device features a VSWR of 1.25:1, with average forward power handling of 5 W and peak power of 30 W. Reflective power ratings are 2 W average and 0.25 W peak. Constructed from passivated stainless steel with gold-plated contacts, it measures 0.5 x 0.5 x 0.7 inches and operates up to +75°C.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance in the E-band microwave spectrum
• Utilizes robust passivated stainless steel construction for durability
• Supports significant forward and peak power handling capabilities

RF Circulators And Isolators Applications

RF Circulators And Isolators Procurement Notes

Verify that the specific model suffix matches the required frequency band and interface dimensions. Confirm that the mechanical footprint aligns with the system waveguide layout. Ensure environmental specifications meet the operational temperature requirements. Check contact plating specifications if corrosion resistance is critical for the intended application environment.

RF Circulators And Isolators Selection Notes

Select this component when operation within the 27–31 GHz range is required. Consider the 20 dB isolation level for adequate source protection. Evaluate the 0.6 dB insertion loss against system link budget constraints. Assess the 30 W peak power rating against potential transient load conditions to ensure reliable operation without damage.

RF Circulators And Isolators Part Context

This part belongs to DiTom Microwave's line of passive RF components. It serves as a directional coupler variant that allows signal transmission in one direction while attenuating reverse signals. Such devices are essential for stabilizing oscillator outputs and protecting sensitive transmitter stages from mismatched loads.
