analoglib relay

hi everyone

I use the relay from analoglib as an ideal switch for simple track and hold, but when I simulate it i have this problem that the accuracy of circuit(tacking fft)is degraded in the input frequency over 10MHz,I reduce the rc time of circuit but the result does not change . For low freq i have no problem fin=100k,is the relay freq depended component?

in the attached pic.

relay:ron=1m rc=1000T! ohm/ Cf=10f

diff input signal(each input vsin has :amp=0.5v offset=0.9v freq=100M*409/4096 second source has thge phse of 180')

the sampling freq(ph1):

tr=tf=50p,pw=4.8n,priode=10n,delay time=100p,v1=0,v2=1.8

strobperiode=10n,strobedelay=8n,runtime=40960ns

i take fft from diff output(vi1-vi2)

Can you just post the input.scs - it's quicker than having to draw the circuit, guess what your input stimulus is, and figure out what you're doing.
Thanks,
Andrew.
