Electromechanical relay, SPDT, 5V

Very good characteristics up to 3 GHz

• > 70 dB isolation, < 0.1 dB insertion loss @ 400 MHz
• > 50 dB isolation, < 0.6 dB insertion loss @ 2000 MHz

RK1 is an electromechanic coaxial relay. It can look like a common relay for p.c.b. but the internal mechanic is very refined and designed to reach a high isolation and a very low loss. It has SPDT contact (two ports switch) and it is available with standard or latching coil. Aside there is a test report on isolation and insertion loss that we made in our lab.
A high value of isolation is reached because the open contact is two times isolated from the common by two ground pins. Standard RK1 electric diagram (non-latching)
