Series 3407 lightning EMP protectors Quarter-wave stub technology with integrated high-pass filter Description HUBER+SUHNER quarter-wave lightning protectors with integrated high-pass filter feature an added useful RF component to the proven premium standard quar- ter-wave protector design. Thus, they can offer an essentially improved protection performance. Features • Residual voltage reduced by 80 % compared to standard types of series 3400 • Residual energy reduced up to factor 2000 (more than 99.9 %) compared to the series 3400 • DC-blocking on protected side of the device (galvanic isolation) • Available for applications from 70 MHz to 18 GHz (N, SMA) General specification Electrical data RF characteristics Impedance Frequency range Return loss (RL) Insertion loss (IL) Passive intermodulation (PIM) RF power transmission Protection characteristics Surge current handling capability (shorting stub design) Residual pulse voltage and energy 50 Ω according to product detail specification, 20 dB min. 0.2 dB max. according to product detail specification (data sheet) according to product detail specification (data sheet) test pulse N 7/16 8/20 µs multiple 10/350 µs 50 kA 25 kA 50 to 100 kA 50 kA refer to product detail specification (data sheet) for typical values refer to the following diagram 58
