High Frequency (RF) Relays

The ARJ22A12X is a high frequency (RF) relay manufactured by KEYES, a market leader in the electronic component industry. It is an RF (Radio Frequency) SPDT (Single Pole Double Throw) relay with a maximum switching capacity of 12Vdc at 1A. This relay is designed for switching RF signals from low to high frequencies, such as satellite signals, and is suitable for signal-level applications.

ARJ22A12X Application Field

The ARJ22A12X is a versatile high frequency (RF) relay that is suitable for a number of applications. The relay is particularly well suited to applications where a rapid switching time is required, such as in satellite communications systems. The relay can also be used for signal-level switching in mobile networks, base transceiver stations (BTS), sound systems, and digital radio broadcast systems.

ARJ22A12X Working Principle

The ARJ22A12X utilizes N/P (noise/pulse) type switching technology to provide high frequency (RF) signal switching. This switching technology works by using a switching coil to induce a current in the relay contacts. When the coil is energized, the current in the contacts increases, resulting in an open contact. When the coil is de-energized, the current decreases and the contacts close.This relay has a wide operating temperature range of -20 to +70°C, making it suitable for a range of operating environments. The contact resistance of the ARJ22A12X is 0.2 to 5 Ohms, and the insulation resistance is greater than 1M Ohms. The relay is also protected against reverse polarity and surge current.

Conclusion

The ARJ22A12X is a high frequency (RF) relay manufactured by KEYES that is suitable for a range of applications. It is an RF SPDT relay with a maximum switching capacity of 12Vdc at 1A, and utilizes N/P type switching technology to provide rapid switching. The ARJ22A12X has a wide operating temperature range, low contact resistance, and is protected against reverse polarity and surge current.
