MEDER electronic CRF Series 7 GHz High Frequency Reed Relay for 50 Ω Impedance DESCRIPTION The MEDER 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. Capable of switching up to 7 GHz with <40 ps rise times for digital operations, this leadless 50 Ohm reed relay is the smallest in the industry and switches into the billions of operations. Capable of withstanding reflow-soldering operations up to 260°C, the relay uses no internal solder and has 1 µV typical thermal offset. Measuring only 8.6 mm x 4.4 mm x 3.4 mm, the leadless design eliminates skewing of leads and co-planarity issues.
