High Frequency (RF) Relays

The ARN30A12 relay is a high frequency (RF) relay, which is used for high frequency applications and frequency transmission systems. It is particularly suited for applications in the Microwave frequency range. This relay is also known as an active device in the circuit, as it is actively used to control the switching of circuits. It can therefore be used wherever accurate and reliable switching of circuits is necessary.

The ARN30A12 is a high frequency relay that operates within the 12GHz frequency range. It has a low insertion loss, high isolation, and high switching speed. It also has a low current consumption and can withstand high power input. Additionally, it has a wide operating temperature range of -55°C to +125°C, making it suitable for a wide range of applications.

Application Field

The ARN30A12 is widely used in high frequency applications and RF systems for switching and frequency transmission. It can be used in a wide range of applications, including antenna systems, antenna amplifiers, RF amplifiers, RF switches, wireless transceivers, satellite systems, and military applications. Additionally, it is used in low-temperature cryogenics, military communication systems, microwave transceivers, and post-amplification systems. Furthermore, it is suitable for applications where high performance, low power consumption, and low standby current are needed.

Working Principle

The ARN30A12 relay is a passive high frequency relay that operates through an internal metal-oxide-semiconductor field-effect transistor (MOSFET). It is usually used in 2-pin and 4-pin configurations. The internal MOSFET is connected in series with a pair of contact closure (CC) leads in the form of a double-pole, double-throw (DPDT) switch. The contact closure’s arms are driven by an external capacitor, which, in turn, is driven by an external voltage. This capacitor acts as a noise filter, increasing the relay’s RF isolation and immunity from interfering signals. Additionally, the relay itself has an internal capacitor that helps further reduce RF noise propagation.

The internal MOSFET allows the switch contacts to be opened and closed according to the voltage applied to the relay. The voltage applied to the relay depends on the type of application, the frequency, and the power of the signal. Generally, the voltage applied to the relay should be between 4–15 V. When the voltage applied to the relay is greater than the threshold voltage of the internal MOSFET, the current starts flow through the relay and the switch contacts close. When the voltage is equal to or lower than the threshold voltage, the switch contacts open again.

The ARN30A12 relay offers high-quality RF isolation, as it is rated for isolation up to 1GHz. It also has a high switching speed of up to 10GHz/s, making it ideal for applications where fast switching is essential. Furthermore, its low insertion loss of 0.15dB ensures that signals passing through the relay are not significantly attenuated.

The ARN30A12 relay is an essential component of any high frequency or RF circuit, as it is used to switch signals accurately and reliably. In applications where RF noise must be minimized or eliminated, or where fast switching of signals is necessary, the ARN30A12 relay provides a great solution.
