Application Notes
A. Materials used in the products are UL94-V0 recognized.
Products meet requirements of IEC 695-2-2 (Needle Flame Test).
B. For additional impedance ratios and frequency ranges, please
contact Applications Engineering.
C. For performance plots of CX2148 and CX2148A, please contact
Applications Engineering.
Notes from Tables
1. Impedance and turns ratios are specified primary:secondary.
(CT=Center Tap).
2. For
CX2148 and CX2148A
, Insertion Loss, Amplitude Balance
andPhase Balance are measured on balanced side (secondary
output pins 1 and 3) relative to ground pin (pin 2).
