What are High Frequency and RF Relays?
High frequency and radio frequency switching functions are performed by using relays for radio signals. Lots of applications have been found for these relays, including communication devices, testing, and radio broadcast devices. They are required to monitor the high current frequently found at high frequencies, which typical relays cannot administer. Enrgtech components have high frequency and radio frequency relays from leading brands, including Panasonic, Omron, TE Connectivity, and Teledyne.
Typical applications
The main uses of the high-frequency spectrum are:
- Military and governmental information and communication systems.
- Air force or aviation air-to-ground information and communications.
- Amateur radio.
- Shortwave international and territorial broadcasting.
- Maritime sea-to-shore and ship-to-ship services.
- Over-the-horizon radar systems.
- Global Maritime Distress and Safety System (GMDSS) communication.
- Citizen's Band radio services worldwide (generally 26-28 MHz, the higher portion of the HF band that behaves more like low-VHF).
What are HF and RF relays used for?
High Frequency & RF relays offer a technique to separate circuits in a high-frequency environment as the frequencies employed in electronic devices keep rising. Any application where a very high-frequency electronic signal is being created can utilize high-frequency relays. This comprises computers, industrial machines, and communication devices. In radio applications, RF relays are frequently found in testing apparatus and radio broadcasting equipment. The different circuit systems in radios that are used for sending and receiving must be activated by RF relays.
Types of HF and RF relays
Relays for high frequencies and RF can be constructed with unique characteristics. They can be constructed to be wash tight, flux resistant, immersion cleanable, or have minimal power. There are other solid-state variations of these relays. On HF, global communication is conceivable when all conditions are ideal. It has been feasible to communicate across and across continents and seas many prior times. In the worst-case scenario, no communication outside the constrained groundwave routes is feasible when a band is "dead," regardless of the amount of power, antennas, or other technologies used.
