Characteristic Impedances

[William M. Spaulding, SR]

Gang-

Can anyone tell me the design values for the termination impedances for both the bandpass and lowpass circuits.  I'd be ever so happy if it is 50 Ohms.

Thanks,
Bill

Which filters are you referring to?  If it is the K2, clearly the BPF's are
50 ohms in and out.  It is not so clear about the LPF.  It could be doing
some impedance transformation to match the output impedance of the amplifier
on different bands.

50 ohms in/out, all BPFs and LPFs. If not, let me know and I'll fix it
next rev.  :)
