filtering of LO signals
Hi,
In my dual conversion receiver, I have a 45.455MHz second LO and a 45 - 75MHz first LO. First IF 45MHz second IF 455KHz Both these feed double balanced diode 7dBm mixers. Also I have not filtered these signals at all, and the first harmonic is roughly -20dBc - -30dBc. Is it imperitive that I filter these for my receiver to work? If so by how much? Best regards, John. |
