The TA1800 is a fast pulse preamplifier with a signal bandwidth of 1.8GHz. A unique feature for such high speed amplifiers is the DC coupling. DC coupling avoids count rate effects due to non DC balanced pulse trains and the corresponding coupling capacitor charging.
A test with a 30mV P-P pulse and a P7889 100ps TOF analyzer showed an improvement of 10...15% in peak width (FWHM) when a TA1800 was used for amplification of the small pulse signal.
