    Inverter circuit for Panasonic microvave

    I am searching details to get parts for repairing a defective inverter circuit, model F606Y8X00AP that is used for Panasonic microwave oven, model NN-P295WF? What are the weakest parts (Rectifier, transistor, IGBT and so on)?

    Etna Microwave/Oven automatically resets after 3 seconds of operation

    Hi all, I really hope you guys can help resolve this mystery. Thanks in advance for your consideration. Recently, my microwave/oven combination (Etna CM751ZT/E01) stopped working. As the display wouldn't even turn on, I opened it up to check for any faulty fuses or thermal cutoffs. I did...

    Bad microwave PCB?

    Recently my microwave would shut off after only a minute of operation. Shut off as in a complete shut down of the machine-no power to the display and the buttons were inoperable. After unplugging and then re-plugging in the unit, it would work again but only for about 45 seconds and then shut...

    Unexplainable RF Power levels

    I have an RF Explorer to use to scan what RF's are around me. I am curious as I'm am just getting in learning about wireless transmission and propagation. However I can't explain these power levels of -10 dbm all the way to -0. The RF Explorer does seem to be working correctly just based off of...

    Microwave detection circuit verification

    Dear all, I want to develop a circuitry which is able to detect electromagnetic waves(radio-wave , micro-wave). This circuit will just act as a tamper detect and not physically measure/compute the radiation. I have designed the circuit using toroid ring and few Schottky diodes. The calculation...

    why does 1/4 wavelength have a ground plane and 1/2 wavelength needs no?

    why does 1/4 wavelength have to have a ground plane and 1/2 doesn't? I know that an antenna that has half a wavelength does not need the ground plane (example a dipole antenna) and when using a wavelength of 1/4 it is usually necessary to have the ground plane (planar antennas [PCB]). My...

    Master thesis question

    Hey guys! I’m a EEE student and will be a finalist next year! I need to chose a project for my master thesis and I’m sort of unsure. I’ve always loved wireless/RF communications, specially microwave systems, but I am unsure about what to do for my thesis. I shortlisted 3 main things: -Anti...
