The 8447C Broadband Amplifier combines high reliability and convenience. The performance of this amplifier qualifies it for a number of uses: to improve sensitivity of counters, spectrum analyzers, RF voltmeters, EMI meters, power meters and other devices without distortion or degradation of amplitude accuracy, to increase the maximum power available from a signal generator or sweeper. Covers frequency range from 30 to 300 MHz with typical 3 dB bandwidth from 10 to 400 MHz. Gain (Mean) is 30 dB, ±1 dB with flatness across full frequency range of ±1 dB and VSWR of <2. Impedance of 50-ohms with max. input of ±10 VDC. Option 002 impedance 75 Ohm
