I have uploaded the new BPF board design to my website at <http://users.wildblue.net/wb6dhw>
The values in the schematic still may be changed slightly. The 6 filters are designed to cover from 1.5 to 30 MHz. The filters can be up to 7 pole Elliptical. The coil pads should accept anything from a 0603 thru a 1008. The caps are 0805. I may widen some filters slightly because analysis shows that with the component tolerances, a hole could be created between the top freq.of one filter and the bottom freq. of the next. As stated before, I added a 1 to 1 mini-circuits transformer on the input and separated the power ground from the signal ground. I am currently working on an enclosure made of pc board for the 5 boards to provide a stable test platform before testing the remaining boards. Eventually, I will post the enclosure design on the web site as well. Dave - WB6DHW ------------------------ Yahoo! Groups Sponsor --------------------~--> See what's inside the new Yahoo!
