Strange results simulating 10MHz passive bandpass filter.

[david_c_partridge]

I'm simulating a 10MHz bandpass filter in MS14.1

Input is a 0-5V clock signal series 50R into bandpass.  When I scope the output I see 7.29Vpp when unloaded (i.e R2 not present), when I add R2 so the output is into 50R, then I see 5Vpp???

Neither makes a lot of sense - who ever heard of a passive bandpass filter with gain!!!

I can't see what I'm doing wrong here (if anything)?

Thanks

David
