RF Power Capabilities of the IXRFD615X2 MOSFET Gate Driver in a Resonant Full-Bridge Configuration The dual 15 A MOSFET driver is evaluated in a resonant full-bridge circuit to compare operation against an operating the previous-generation DEIC420 MOSFET gate driver in a resonant half-bridge circuit.

Simulations for both full-bridge and half-bridge configurations are presented to complement and verify circuit operation. This circuit can also be used as a medium-power RF source for applications where a compact RF source is required.


RF Power Definitions Technician Note 003 Manufacturers and customers do not always use the same power definitions for their applications. This application note provides definitions for commonly used RF power terms. 2013

P1dB and P3dB Definitions Technician Note 002 P1dB, the output power at 1 dB compression, is typically used when referring to amplifiers. It is defined as the output power level at which the actual gain deviates from the small signal gain by 1 dB. Similarly, P3dB is the power level at which actual gain deviates from small signal gain by 3 dB. 2013

Gate Charge Technician Note 001 Gate charge is a parameter that can be used to estimate MOSFET turn-on time if the gate current is known, or estimate the gate current required for a desired turn-on time. This parameter is dependent on drain voltage and temperature. 2013

DEIC420 and IXDD415 SPICE Model This application note describes a PSpice model for the DEIC420 and IXDD415 gate driver ICs. 2003

DE Series MOSFET and Driver Installation and Mounting Instructions The DE-Series MOSFETs or ICs may be mounted in three different configurations, depending upon the application and power dissipation required. This document refers to MOSFET mounting, however these mounting instructions also apply to the gate drive ICs packaged in the DE Series packages. 2003

Thermal Resistance and Power Dissipation The thermodynamics of power semiconductor devices can be complex and confusing. The following article will present two sets of the most important specifications in this area, the thermal resistance (Rθ) and the power dissipation (PD). 2003

PRF-1150 1 kW 13.56 MHz Class E RF Generator Evaluation Module The PRF-1150 module is a self-contained 1KW 13.56MHz RF source. The module facilitates operation and evaluation of the IXRFD630 RF MOSFET gate driver IC and DE275X2-102N06A RF MOSFET in a practical 13.56 MHz RF generator application. It is all-inclusive, pre-tested, and ready to operate. 2002

RF Power Capabilities of the DEIC420 MOSFET Driver IC at 3.6, 7, 10 and 14 MHz 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.

NOTE: The DEIC420 has been discontinued, replaced by the IXRFD630 CMOS Gate Driver. This application note is for reference purposes only.

The Destructive Effects of Kelvin Leaded Packages in High Speed, High Frequency Operation Today power MOSFET die technology is not the only limiting factor in achieving the high switching speeds and higher frequencies targeted as goals by the RF and HF power communities. The choice of the package is often the fundamental cause of most of the problems found when attempting to operate power MOSFETs at high switching speeds and high frequencies. These problems can appear as unstable operation in the most benign conditions and as an unexplained failure and radically reduced reliability in the worst cases. This paper explores in detail the impact of intermediate speed enhancement techniques, such as the Kelvin lead, without commensurate attention to other stray inductive terms. 1998
