D4I1922

RF Circulators And Isolators Overview

The D4I1922 is a microwave isolator manufactured by DiTom Microwave, designed for operation within the 19 GHz to 22 GHz frequency range. This component features SMA female connectors and is housed in a module format with SMA connector interfaces. It supports an average forward power of 10 W and provides an isolation level of 44 dB. The device exhibits an insertion loss of 0.8 dB and a Voltage Standing Wave Ratio (VSWR) of 1.2. It operates within a temperature range of -20°C to +65°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance of 44 dB within the specified K-band frequency range
• Supports continuous average forward power handling up to 10 W
• Features low insertion loss of 0.8 dB for efficient signal transmission
• Utilizes SMA female connectors for standard interface compatibility

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement equipment operating in the 19-22 GHz range
• Radar systems utilizing K-band frequencies

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version and electrical tolerances prior to integration, as specifications may vary between manufacturing batches. Confirm that the SMA female connector configuration aligns with the system's interconnect requirements. Ensure that the thermal management design accommodates the specified operating temperature range of -20°C to +65°C to maintain performance stability under load conditions.

RF Circulators And Isolators Selection Notes

Select this model when a high-isolation value of 44 dB is required for the 19-22 GHz band. The 10 W power rating makes it suitable for moderate power applications. Compare against lower isolation variants like the D3I1922 series if reduced cost or different isolation levels are acceptable. Ensure the SMA female interface matches the mating components in the RF chain.

RF Circulators And Isolators Part Context

This component belongs to the D4I1922 series of RF isolators from DiTom Microwave. It is part of a family of microwave components designed for K-band applications. The series includes variants with different isolation characteristics, such as the D3I1922, which offers lower isolation but potentially different insertion loss profiles. These devices are categorized under RF circulators and isolators for wireless communications.

RF Circulators And Isolators Replacement Considerations

The D3I1922 is a related variant within the same product line, offering 22 dB isolation instead of 44 dB. Verify if the reduced isolation specification meets the system requirements before substitution. Both parts share similar frequency ranges and connector types.
