Hi I am a rookie on both RF and PCB design and I am currently trying to do a 50 Ohm 11 Watts Dummy Load project for 100MHz-1GHz. My calculations are done for the load but I have some questions about designing the PCB.
I am trying to do it as a microstrip line and as a simple structure of the...
I am trying to build a lock-in amplifier circuit using AD630. But the signal which I wanted to detect is in the megahertz range and AD630 is not functioning in this region. So, is there any device which can do lock-in like AD630 but in a higher frequency region?
I have recently acquired a high frequency stabilizer which allows an AC welder to weld aluminum using TIG equipment. I am new to TIG welding but want to learn more about it and this seemed like a good way of getting into it. I have been having a tough time welding with it though. I have had some...
I'm working on dimming a high-wattage LED (50W--12V/4.17amps) with a 3.3V micro-controller. The solution that has worked so far is by using a low-side (PNP) MOSFET to drive the LED and a NPN transistor to drive the MOSFET via the 3.3V signal from the MCU. At 488hz PWM I can dim the LED light...
The wall power is rated at 50 to 60 cycles per second. I want to feed a circuit with that energy (50 - 60 Hertz) and obtain a higher frequency output, pure sinusoidal wave. Preferably, it can be tuned from around 100 hertz to 30 kilohertz.
The output wattage must be at least 300 watt.
