After beginning with the devel general interest to design engineers is the Step Recovery Diode. This de opment of specialized silicon, germa vice has made possible advances in nium, and gallium arsenide diodes, fast pulse work and is unique as an hpa has gone on to achieve industry efficient generator of high-order har leadership in metal-on-semiconduc- monics. These capabilities are de tor ("hot carrier") technology and is scribed in the following article. Fig. 1.
