Gain Linearity
The gain deviation relative to the gain at –10 dBm0 is within the limits shown in Figure 3 (A-law) and Figure 4
(µ-law) for either transmission path when the input is a sine wave signal of 1014 Hz.
Note:
Relax specification by 0.05 dB at –40°C.
Note:
Relax specification by 0.05 dB at –40°C.
