Application Notes
A .Bandwidth specifications are for a
75
W
system.
B. 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. Contact
Pulse Applications Engineering for
extended temperature performance data.
4. Return loss performance changes with
change in temperature.
Performance warranty of products offered on this data sheet is limited to the parameters specified. Data is subject to change without notice. Other brand and product
names mentioned herein may be products and/or registered trademarks of their respective owners.
