400 W / 1.6-54 MHz reference design using 2x SD2933

STEVAL-TDR004V1

Overview

The STEVAL-TDR004V1 demonstration board is an RF broadband power amplifier intended for linear or nonlinear operation over the 1.6 to 54 MHz band, using two SD2933 gold metallized Nchannel MOS field-effect transistors. The temperature compensating biasing circuit supports class B and class AB operation.

STEVAL-TDR004V1 is designed in cooperation with Specific RF Devices (Germany).

Pay attention to technical details in LED lighting design
LED light source technology is becoming more mature, and the luminous lumens per watt are increasing rapidly, which has led to a gradual price reduction. For example, the price of a 1W LED light sourc
CC2420 hardware address recognition problem
I use ZigBee to make a wireless alarm substation. The sensor transmits data to the substation through ZigBee. In order to distinguish each sensor, I turned on the module's hardware address recognition
STM32 built-in DAC output voltage amplified to drive piezoelectric ceramics
As shown in the figure, the output of the built-in DAC of STM32 is a step wave, which is amplified by the amplifier circuit to drive the piezoelectric ceramic. However, after the piezoelectric ceramic
f5529 and GPS communication restart problem
I made a product in the lab. GPS communicates with f5529, and 5529 sends the received GPS data to GPRS. However, when communicating with GPS, f5529 always restarts uninterruptedly. I don’t know why. I
Help --Application of Mechanical Filter for Remote Multi-point Control
This design requires using a single-chip microcomputer or single-chip microcomputer to control DDS to generate signals of multiple frequencies, and then use a mechanical filter to receive them at the
DirectShow capture problem
I developed a capture program using DirectShow under wm6.5, using PIN_CATEGORY_STILL. After the program runs, I use the rear camera to capture images, and the output is normal. When I switch to the fr
