Re: T41 BPF results
¿ªÔÆÌåÓýI¡¯ve made these changes to the assembly manual and the BOM for the BPF¡ Looks very good.? The loss looks like about 3db maximum and that is easily made up by the RF amp in the front end.? Also, that loss could easily be die to the switches (guess I can test that in bypass mode as that had no filter/ loss elements but does have the two switches). ? I¡¯ll add a loss table (max loss per band) if anyone makes those measurements¡ ? This would be a nice exercise for the LPF too¡ ? ? Dr. William J.
