Inquiry (采购产品): Need Technical assist I have 2 Lumped Constant filter designs I need to convert to analogue active filters. I am quite familure with passive filter design but need a lot of help in picking the amplifiers & best approach to do the job. These are: 1- 7 coil elliptics CF=1.5Mhz, BW approx 200Khz The other is CF= 7Mhz, BW= 1Mhz & uses 4 coils. In addition, I need info relating to Impedance transformation, Return loss (or VSWR), In/out voltage range, degradation of response due to component variation <+/-1% & any parasitic responses I might see. Our customer requests quan's of each from 100 to 1000 of each Please call as this is an immediate requirement. Thank you **** Hidden Message ***** Jerry Buckwalter 1106 E.
