High Frequency (RF) relays are widely used in the telecommunications industry due to their ability to switch high-frequency signals with low-passive intermodulation (PIM) losses. 2653-05-320 is a high frequency RF relay that can support frequencies ranging from 0.6 GHz to 4.9 GHz.

The 2653-05-320 is designed with a latching solenoid which can be triggered on or off by direct current (DC) current. It uses a high-force magnetic latching system, where an initial current pulse is used to “pull” the contacts together, and then a subsequent pulse is used to “unlock” the contacts. This design eliminates any need for a power source to maintain the contact status.

The 2653-05-320 has a low contact resistance when in the “on” position, providing low insertion loss and extremely low PIM levels (<70dBc). The relay also features a high isolation rating when in the “off” position, ensuring that there is no cross-talk between channels.

The working principle of the 2653-05-320 RF relay is based on electromagnetic latching. When the DC power is applied, the coil creates an oscillating electromagnetic field, which amplifies the signal passed through it. This amplification of the signal pulls the two contacts together and latches them in place. When the power is removed, the contacts remain latched and the signal can continue to pass through.

The 2653-05-320 is designed for use in a variety of applications, including cellular base station transmitters and receivers, and cable TV transmitters and receivers. It is also used in radio and satellite communication systems, and it is compatible with wireless LAN’s and microwave links. Additionally, the relay can be used in instrumentation and test equipment, amplifiers, transceivers, and other high-frequency RF applications.

Overall, the 2653-05-320 RF relay is an efficient and reliable switching device, making it an ideal choice for a variety of RF applications. With its low contact resistance, high isolation rating, and low PIM losses, the relay ensures a high-performance signal without introducing any distortion or signal loss.
