What is the main function of fixed attenuator

(1) Adjust the size of the signal in the circuit; (2) In the comparison measurement circuit, the attenuation value of the network under test can be read directly; (3) If some circuits require a relatively stable load impedance, an attenuator can be inserted between the circuit and the actual load impedance to buffer the change of impedance.

If I exceed the maximum input level, will I burn out the fixed attenuator?

This is not recommended as it may cause data distortion or burn down attenuators.

All of HBTE fixed attenuators are tested and specified at 50Ω impedance, can I use them at 75Ω?

It is not recommended. If you need key specifications for the 75 Ω system, please contact our salesman. Our engineers will redesign the internal components for you to meet specific requirements.

Helical Antenna

Helical antenna is a spiral-shaped antenna, which is composed of spirals with good conductivity and can transmit and receive polarized electromagnetic signals rotating in space.HBTE provides you with superior performance of backcavity helical antennas and conical helical antennas, with excellent impedance matching and radiation pattern. It can be used as a separate antenna component or as a feed for reflector satellite antennas.
