High Frequency Relays |

High frequency reed relays are capable of switching signals from DC up to 7 GHz. This is achieved by keeping the signal path as short as possible.  Additionally the relays use 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. Their cost is moderate and stable. Their size is becoming smaller and smaller.
