["The TBFL1 is a combined transient limiter, attenuator and high-pass filter in one. It is looped into the signal path to optimally protect the input of the spectrum analyzer or measurement receiver. This applies in particular to the measurement of conducted interference emissions or other measurements where the input level cannot be predicted or where random overloading can occur. So-called PIN and Schottky diodes combined with a multi-stage 10 dB attenuator result in a device that can withstand continuous RF input levels of up to 5 W (37 dBm). A gas discharge tube provides additional protection from high voltage transients. In addition, the 9 kHz high-pass filter suppresses harmonics that come from the mains voltage. With a threshold level of +11 dBm and a flat frequency response in the range 9 kHz to 600 MHz, the TBFL1 can be used universally in the entire range of conducted interference emissions and many other applications", "General application for limiting high-energy RF pulses", "Transient limiter for measuring conducted interference", "Frequency range: 9 kHz to 600 MHz", "Attenuation: 10 dB – 0.5/+1.2 dB in-band (9 kHz..600 MHz)", "Attenuation high-pass filter: > 30 dB @ 2 kHz", "Maximum continuous RF input power: 5W (+37dBm) in-band", "Maximum DC input voltage: ±20V", "Input matching, linear working range: 9 kHz..600 MHz < -16 dB", "Input matching, linear working range: 9 kHz..600 MHz < -23 dB", "Linear working range: up to 0 dBm input level, in-band", "Threshold: +11 dBm (@ 37 dBm input level)", "Input connection: N socket", "Output connection: N plug", "Dimensions: 156mm x 26mm x 26mm", "Weight: 170g", "Transient limiter/attenuator/high pass filter in wooden box"]
