Characteristics
Remark:
The reference level for the relative attenuation arel of the 70AG is the insertion loss. The attenuation at the nominal frequency is defined as the insertion
loss ae. The nominal frequency fN is fixed at 70 MHz without any tolerance or limit. The values of relative attenuation arel are guaranteed for the whole
operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.

Interchannel Performance after removal of Bias Interchannel Performance is defined as the greatest phase or gain difference between cascaded pairs
over the specified passband. An offset (bias) may be removed before each measurement
4
Phase and gain matching over temperature measures the change in the difference between two cascaded pairs as the temperature is varied from
+40°C to +50°C
