High-Frequency Performance
In 50
systems, signal response is reasonably flat up
to 30MHz (see Typical Operating Characteristics).
Above 30MHz, the on-response has several minor
peaks that are highly layout dependent. The problem
with high-frequency operation is not turning the switch
on, but turning it off. The off-state switch acts like a
capacitor and passes higher frequencies with less
attenuation. At 10MHz, off-isolation is about -46dB in
50
systems, declining (approximately 20dB per
decade) as frequency increases. Higher circuit imped-
ance also diminishes off-isolation. Adjacent channel
attenuation is about 3dB above that of a bare IC socket
and is due entirely to capacitive coupling.
