Description
The TA2400 is a fast preamplifier with a small signal bandwidth of 2.4 GHz.
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 charging of coupling
capacitors.
Basically the TA2400 is a non inverting, closed loop, voltage mode, operational amplifier design.
A test with a 30 mV
improvement of 10 ... 15% in peak width (FWHM) when a TA1800 (1.8GHz / 20dB / x10) was
used for amplification of the small pulse signal.
Applications for the TA2400 are:
•
Pre-amp for ultra fast detectors (MCP, PMT, ...)
•
Oscilloscope and transient recorder pre-amp
•
Photon-/Ion-counting
•
Wideband signal processing
