A class E power amplifier working at 1 GHz and with an LDMOS transistor as switching element has been developed. The circuit is implemented with lumped and distributed elements. An output power of 6.2 ...

The celebrated ‘555’ IC was originally developed as a timer device, but over the years this golden oldie has been used in all sorts of other applications, including some never imagined by its ...

Class D amplifier is rarely reported to be broken when it is operating with a fluctuating load. This is because excessive voltage or current is imposed on the transistor of the class D amplifier.

When all else fails, ham radio,” said club member John Kowalk, who has been doing amateur radio since the 1950s. Kowalk said ...
