WIDEBAND RF TRANSFORMERS
Upstream Transformers for Set-Top Box
and Cable Modem Applications
Application Notes
C. Materials used in the products are UL94-V0 recognized.
Products meet the requirements of IEC 695-2-2 (Needle Flame
Test).
Notes from Tables
1. Impedance and turns ratios are specified primary:secondary.
(CT=Center Tap).
2. Bandwidth is referenced to midband loss.
3. The insertion loss of these transformers is verified from -40°C
to +85°C. Insertion loss over this temperature range is less
than 1 dB from 5-80 MHz (relative to midband loss).
4. Return loss performance changes with change in temperature.
