[Moon-net] Dealer for LNAs inkl Cavity -----

[ON4KHG]

Hi Walter,


Don't expect to have a so narrow BW out of a cavity, especially with the 
ATF54143 or 33143 that need a relatively low impedance on their gate. Hence, 
they load a lot the cavity and the BW extends accordingly. Better use a 
"normal" preamp (and less space consuming) and insert a notch filter in 
front of the preamp, though at the expense of a few tenth of dB of NF loss. 
Have a look at the website of Michel, ON7EH :

Best 73's,

Gaëtan, ON4KHG
