High Frequency (RF) Relays are used mainly in applications involving radio frequencies above 10 kHz, though some are rated for higher frequencies. They are used for amplifying, controlling, and switching of high-frequency signals. One such relay is the ARXP114H. This article will cover the application field and working principle of this type of relay.

The ARXP114H relay is designed primarily for use in military and commercial applications, including radar, communications, test equipment, medical equipment, and high power switching. It features a rugged construction and is designed for very high-frequency switching and control, up to 6GHz. It is capable of handling high power levels, up to 10W.

The ARXP114H relay is a fully enclosed, single-pole, double-throw (SPDT) device. It is most commonly used as a switch, allowing high-frequency signals to be switched between two states. The contacts are shielded to prevent interference, and the coil actuation is done using a 12V DC at 1A.

The ARXP114H is an example of a latching relay, which means that the contacts stay in either one state or the other until the coil is actuated again. This is useful for applications where a signal needs to be on continuously, such as in a radar system. When the coil is not energized, the relay is in the "normal" closed position (NC). When the coil is energized, the relay is in the "reverse" open position (NO).

The ARXP114H also features a normally open (NO) contact which is energized only when the coil is not energized. This is useful for applications where a signal needs to be on only briefly, such as for a safety interlock. The NO contact is often connected to a second relay, allowing the first relay to control the second relay\'s state.

The ARXP114H is ideal for radio frequency switching and control, as it can handle high-frequency signals and high power levels. It is reliable, and its latching feature ensures the switched signal is maintained for as long as desired. Its NO contact feature also makes it a good choice for safety interlocks and other applications where a signal needs to be on only briefly.
