• Satellite ground station components

RF Circulators And Isolators Procurement Notes

Verify the exact part number suffix against official DiTom Microwave documentation to ensure correct connector gender and configuration. Confirm that the required frequency range aligns with the 17.00–20.00 GHz specification. Check RoHS compliance status if environmental regulations apply. Ensure thermal management solutions accommodate the specified operating temperature range of -30°C to +65°C. Validate mechanical dimensions fit the intended assembly space.

RF Circulators And Isolators Selection Notes

Select this component when a fixed-frequency isolator is required for the K-band range. Consider the SMA-FEMALE interface for mating with compatible cables or modules. Evaluate the 10 W power limit against system peak power levels. Assess the 44 dB isolation requirement against system noise floor needs. Compare physical dimensions against available board real estate.

RF Circulators And Isolators Part Context

This component belongs to the D4I series of connectorized ferrite isolators from DiTom Microwave. The series covers frequencies from 400 MHz to 43.5 GHz. The D4I1720 variant serves as the base model for the 17–20 GHz band. The -1 suffix typically denotes specific connector configurations within the product line.
