What is acceptable for group delay?
1 kHz and above – anything less than 2 ms is good. 200 Hz – 1000 Hz – less than 4 ms. Under 200 Hz – Expect higher numbers. Even 30-40 ms for the very low frequencies.
What is group delay in RF?

Group delay is a measurement of the time taken by the modulated signal to get through the system. Group Delay is measured in seconds. For an ideal filter, the phase will be linear and the group delay would be constant.
What is group delay measurement?
There are two primary means of measuring group delay. The most widely used involves frequency domain method converting small-signal S-parameters to group delay. The time-domain method directly measures the time that a pulse takes to move through a network.
