D4I0120-2

RF Circulators And Isolators Overview

The D4I0120-2 is a microwave isolator manufactured by DiTom Microwave, designed for operation within the 1.7 GHz to 2.0 GHz frequency range. This component features SMA-FEMALE connectors and is housed in a module package with integrated SMA connectors. It supports an average forward power handling capacity of 150 W. Key electrical specifications include an isolation rating of 40 dB, an insertion loss of 0.8 dB, and a Voltage Standing Wave Ratio (VSWR) of 1.25. The device is currently in active production status.

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 150 W for robust signal transmission
• Features low insertion loss of 0.8 dB to minimize signal attenuation during passage
• Maintains excellent impedance matching with a VSWR of 1.25

RF Circulators And Isolators Applications

• RF transmitter output stages
• Microwave communication systems
• Test and measurement equipment

RF Circulators And Isolators Procurement Notes

Verify the specific part number suffix against official DiTom Microwave documentation to ensure correct connector configuration and performance specifications. Confirm RoHS3 compliance and EAR99 classification requirements for your region. Check current availability as this item may be subject to order-based supply chains rather than immediate stock. Ensure mating SMA-FEMALE connectors are compatible with your system interface.

RF Circulators And Isolators Selection Notes

Select the D4I0120-2 when operating frequencies fall strictly between 1.7 GHz and 2.0 GHz. Consider its 150 W power handling capability if the application involves high-power transmission lines. Evaluate the 40 dB isolation requirement against system noise floor needs. The SMA-FEMALE interface dictates cable selection and adapter requirements for integration into existing RF setups.

RF Circulators And Isolators Part Context

This component belongs to the D4I0120 series of isolators produced by DiTom Microwave. Isolators are non-reciprocal devices that allow signal flow in only one direction, crucial for stabilizing oscillators and amplifiers. The D4I0120-2 variant specifically targets the L-band frequency range, offering a balance of high power handling and low loss for professional RF applications.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other manufacturers' L-band isolators only if they match the 1.7-2.0 GHz range, 150 W power rating, and SMA-FEMALE interface specifications exactly.
