High Frequency Relays
As package requirements get smaller and micro processors get faster more pressure is being applied to the manufacturers of switching products. MEDER is meeting that challenge with a release of its new high speed – high frequency
reed switching relays.

CRF Series Reed Relay is a low-profile device made with a ceramic case that exactly matches the thermal coefficient of expansion of the
reed switch glass and the reed lead to eliminate any potential packaging stress. This leadless 50 Ohm reed relay is capable of switching up
to 7 GHz with <40ps rise times for digital operations.
