Data Sheet  
These transmission characteristics are valid for 0 to 70º C.  
Attenuation Distortion  
The attenuation of the signal in either path is nominally independent of the frequency. The deviations from nominal attenuation  
will stay within the limits shown in Figure 3 and Figure 4. The reference signal level is –10 dBm0. The minimum transmit  
attenuation at 60 Hz is 24 dB.
