“Stand Alone” RF Power Capabilities Of The DEIC420 MOSFET Driver IC at 3.6, 7, 10, and 14 MHZ.
●Abstract: The DEIC420 MOSFET driver IC is evaluated as a “stand alone” RF source at 3.6, 7, 10, and 14 MHZ. To create up to 47W of CW RF all that is required is a clock oscillator, RF resonant tank, and associated output matching circuitry. This module can be used as a medium power RF source for amateur radio use, a laboratory RF source, a source of sine wave gate drive, and many other applications where a compact RF source is required.
●Introduction: The DEIC420 is a 20A-pk high-speed MOSFET gate drive IC available from DEI/IXYS. It is compact and self-contained requiring only VCC, a 5V TTL clock signal, and appropriate heat sinking to produce a pulsed RF output signal. The addition of a simple L/C resonant tank and an impedance matching network produces a sine wave output to a standard 50Ω load. With the addition of a keying circuit and additional harmonic filtering the IC can be utilized as an Amateur Radio CW source for operation through at least 20 Meters (14MHZ).
