Hi Arief, If you need to go active, then I can add following device from National Semiconductor to Steve's suggestion: LH0032 (still available ?), dual JFET inputs, 100MHz bandwidth and was quite expensive. It worked for me at 38.9 MHz (an European TV-IF frequency), so surely works at 10 MHz. regards, Bart Yageo Europe arief susanto <denmasearief@xxxxxxxxx> 24-01-04 02:43 Sent by: si-list-bounce@xxxxxxxxxxxxx Please respond to denmasearief To: si-list@xxxxxxxxxxxxx cc: Subject: [SI-LIST] bandpass Category: i need to design active bandpass filter with opamp for center frequency 10.740 MHz and 10.660 with 80 KHz of bandwidth ...... do somebody can help me ? --------------------------------- Do you Yahoo!?
