Need an analog bandpass filter (central frequency 50MHz)
My circuit needs a analog bandpass filter and its detail information is as follows,
Central frequency: 50MHz
Pass band width: no less than 300 KHz and no more than 1.5MHz
Stop band attenuation: no less than -20dB
I have designed a LC filter according to the principles on ordinary textbooks. However I found that the value of L is too small (on the level of nH) that cannot be bought easily.
Could someone tell me that how can I acquire this filter?
Thanks in advance.
Best Regards.
