A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It converts between balanced (differential) and unbalanced (single-ended) signals, providing impedance matching and common-mode rejection to improve signal integrity in RF circuits.
The reference range is 1–3000 MHz, but the actual operating bandwidth depends on the specific model and design. Always check the datasheet for the exact frequency limits.
The impedance ratio (e.g., 1:1 to 16:1) should match the impedances of the connected circuits. For example, a 50-ohm unbalanced to 100-ohm balanced system would require a 1:2 ratio. Verify the required ratio with your circuit design.
Insertion loss is typically 0.5–3.0 dB, and return loss is ≥15 dB across the frequency band. These are reference ranges; specific values vary by model and must be confirmed with the manufacturer.
