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.

TO-5 RF Relay - 712 Series Teledyne's TO-5 DPDT relays have become one of the industry standards for low level switching from dry circuit to 1 Amp. Designed for use when close PCB spacing is required, the 712 series have a low coil power dissipation in an ultra-miniature relay package. In addition to the standard types there are the 712 D and 712 TN relays. The 712 D relays have an internal discrete silicon diode which provides coil transient suppression. The 712 TN -5 hybrid relay (stock number 758-2449 ) has an internal silicon diode and transistor driver. The integrated packaging of the relay with its associated semiconductor devices greatly reduces PCB floor space requirements as well as saving on installation time. With a low inter-contact capacitance and contact circuit losses, the whole range of 712 series TO-5 relays are excellent ultra-miniature RF switches for frequencies well into the UHF spectrum (see datasheet for performance curves). A typical RF application for the TO-5 relay is in hand held radio transceivers, the combined features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of Transmit/Receive switching. Hermetically sealed Excellent switching performance from d.c. to 1GHz High resistance to shock and vibration Gold plated contacts Low insertion loss - isolation and intercontact capacitance of 0.4pF Uni-frame design provides high magnetic efficiency and mechanical rigidity High reliability and excellent resistance to environmental extremes Low profile height of 6.99mm
