* Temperature data available upon request.
* Specifications subject to change without notice.
* When compared to competitive parts, Communication Associates Inc.'s couplers typically have similar or less insertion loss with significantly tighter tolerances.
* System impedance is determined by external resistor. Data shown represents 75 Ohm enviroment.
* "Out to Tap" data shown are derived by subtracting "In to Tap" measurement from the actual "Out to Tap" measurement. This is also sometimes referred to as "directivity".
