High frequency reed relay products are capable of switching signals from DC up to 7 GHz, attained by keeping the signal path as short as possible and using an internal coaxial shield with a consistent 50 Ohm impedance path. Not only is it excellent with RF signals, but is also great for digital signals where the skew rates or effects on the rise time of fast digital pulses is less than 40 picoseconds through the relay. Internal magnetic shield prevents any magnetic coupling effects between relays when designing a two dimensional or three dimensional relay matrix. These RF reed relays have a flat frequency response out to 20 GHz. Their cost is moderate and stable. Their size is becoming smaller and smaller.
