No, SAW filters are completely passive devices. You cannot get gain from a SAW filter, and they obey the rules of reciprocity (i.e. S12 = S21).
resistor
scr is active component because it's generated energy or amplified energy
Active means devices that perform functions in a non linear fashion [amplifiers] passive are components that perform according to a set of linear rules
An active filter is a type of analog electronic filter that uses active components such as an amplifier. Amplifiers included in a filter design can be used to improve the performance and predictability of a filter, while avoiding the need for inductors (which are typically expensive compared to other components). An amplifier prevents the load impedance of the following stage from affecting the characteristics of the filter. An active filter can have complex poles and zeros without using a bulky or expensive inductor.
