RF TRANSFORMER
For Wideband RF Applications
1. Impedance and turns ratios are specified primary:secondary. (CT=Center Tap).
2. Bandwidth is referenced to midband loss.
3. These transformers are verified to operate from -40°C to +85°C. Contact Applications Engineering for performance data.
4. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (ex: CX2078NLT).
