wideband output amplifier circuit

Posted on Feb 4, 2014

This is a simple design for wideband output amplifier. The wideband amplifier is suitable for use as a 50 © transmission line driver. This circuit is built by CA3140. This is the figure of the circuit. This circuit, when used in conjunction with the function generator and sine wave shaper circuits shown in Figures 10 and 12 provides 18VP-P output
