Coaxial RF SPD

The radio frequency system usually has outdoor facilities such as antennas, which are prone to lightning strikes. The powerful current and extremely high voltage generated by lightning can invade the system through antennas, feeder lines, etc. Whether your radio frequency application is in CCTV, tower tops, GPS or cellular base stations, PTG coaxial radio frequency surge protectors can provide you with a complete solution. PTG's coaxial products are based on the SPD design concept and have features such as high discharge capacity, low voltage protection level, low insertion loss and multiple connection ports. We can customize the products according to the field application requirements.

Spark Gap SPD with built-in GDT

Spark Gap SPD with built-in GDT

Equivalent to a low-pass filter, filtering unwanted, harmful waveforms and surges.

Suitable for DC transmission applications via coaxial cables, such as remote amplifiers, LNAs, and antenna power supply circuits.

Superior RF protection performance, suitable for IEEE 802.11a, 5.2-5.8GHz ISM, UNII, and 3.5GHz WLL applications.

Based on GDT characteristics and ingenious internal structure design, minimizing fire risks and ensuring reliable signal transmission.

Spark gap type RF SPD supports replaceable GDT function.

1/4λ SPD

1/4λ SPD

Equivalent to a signal bandpass filter, allowing signal transmission only within specified frequency ranges.

Low-frequency characteristics of lightning interference result in SPD short-circuiting during lightning strikes and low-frequency surges, diverting energy to the ground.

Non-GDT design with impact resistance and fast response time for wide application; maintenance-free.

Directly grounded housing with equal protection for both ports, simplifying installation.
