EMI/EMC solutions supplier NexTek has announced a new series of lightning arrestors for protecting high-power radio frequency (RF) transmission lines, including the HF, VHF and UHF frequency ranges from 0(dc) to 1000MHz. The K1 series offers protection for high-power RF transmission lines of up to 50,000 Watts while the T1 series has a transient rating up to 100,000 Amps+.
According to the company, the K1 series product voltage ratings can range from 1.4kV to 3.5kV and exhibit a nominal impedance of 50 Ohms, allowing the K1 to pass up to 30kW or more of RF power. The T1 series provides a 250x multiple strike capacity at 10kA and a 100kA one-time surge capability. Additional specifications for both models include lightning transient protection using a multiple GDT design, low VSWR of 1.20, and insertion loss of only 0.1dB. Both models are compliant with the IP68 standard.
