Here's what I wrote to IK4AUY - did not get an answer. Can anyone on the list help?
Ciao Sergio, In your H Mode Mixer article QEX July/August 2004 there are two noise filters. The article does not give part numbers. Are the Murata EMI filters acceptable for this application? There are two Murata series DSS6 with capacitance range of 47 to 2200 pF and DSS9 with a range of 22 to 22000pF. Physically either style will fit the FAR Circuits board. Which part and how much capacitance should I use? BTW, the FAR Circuits boards are very poorly made - some errors, no solder mask and no plated thru holes. I hope I can make this work Grazie, Larry K3VX
