Abstract
The PRF-1150 module is a self-contained 1KW 13.56MHz RF source. The
module facilitates operation and evaluation of the DEIC420 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.

INTRODUCTION
A
n RF module can be used to demonstrate the capabilities of our DEIC420 RF
MOSFET gate driver IC and DE275-102N06X2A 1000V 6A RF MOSFET at ISM
frequencies. The PRF-1150 module produces 1000W CW of RF output at 13.56MHz.
with 85% DC to RF conversion efficiency. The module is a self-contained RF
generator. To produce 1kW of RF output, only external DC power need be applied.
The module dimensions as shown in Figure 1 are 6.75” x 3.1” x 2.7” including an air-
cooled heatsink and copper heat-spreader. Impingement flow from a standard 4.5”
bench fan provides adequate cooling for the 1kW output level. Standard 0.1” dual and
single row headers are used for DC input to the module and a single right-angle BNC
connector is used for RF output to a 1kW 50Ω RF load or attenuator.

MODULE DESCRIPTION
Please refer to Figures 1-6 during this module description. Low-Voltage DC is applied
to the module via connector J1. 5V @ 30 ma and 15V @ 3A are applied to J1 pins 4
and 2 respectively. LEDs D3 and D5 glow green if the appropriate voltages are applied.
U1 is a 13.56MHz clock providing a 50% DC, 0-5V square wave. U2A provides a pulse-
width adjustable source to drive U4, the DEIC420 gate driver IC.
