Hi,
I have designed a filter at 8.2MHz for the RFIC at the output of a mixer. Its impedance ( input and output) is 1000 ohms. This means higher value of inductors (Lower SRF, Q).It is working fine. But it is of 5th order and hence expensive.

I want to decrease the order. Can I get the same performance by decreasing the impedance and using better Q inductors.

TIA
