Hi all,
I want to make an half duplex RF Switch for antenna to switch from Receiver to Transmitter. I know it can be done using pin diodes and relays. But before implementing the traditional approach, I went for latest available RF Switch ICs. I found some SPST switches but with different...
We have designed a RF limiter in 1.5MHz to 30MHz range with working power level of -40dbm and above. It should not operate in case of weaker signals from -40dbm (FYI our desired range is -120dbm to -50dbm) and start from here to stronger. The problem arising is that it is ON, on all power levels...
Yes I tried that nothing appears as if the circuit is not even present between the test equipment. I have tried this circuit and my own circuits and no results........Will try a new filter this one was a cheap china copy I think.........I can think of no other reason.

Hello All,
Recently I bought a ceramic filter PFS455A of 455kHz for my receiver project. I wanted to test it independently first to see its response on oscilloscope. I made the test circuit mentioned in it's datasheet and connected with signal generator, nothing came on oscilloscope, as if it...
Hello,
I am trying to test a simple BPF in multisim. But it is giving me "matrix singular error" and I can't seem to diagnose the problem.
Here is the circuit, help if possible.
Brian cool down man, if you read my post I haven't once mentioned the word "Better". Or compared Arduino and pic to be superior to one another. I merely said its user friendly and easy to perform small tasks such as Fading LEDs. My advance projects are all on PIC, but even if I'm making a...
I see solutions have already been provided. Although you should use arduino for fading. Its way easy to use than Pic MCU and you can use built in LED to observe the blinking and fading of LED in real time. It takes no time in getting programmed again and again.
Good Luck!
Hello Everyone!
I have just started making a super het transceiver and I'm facing problems in very first section. Right after signal enters through antenna we have an LNA to reduce(not completely eliminate) noise and to amplify the signal as well.
My Question is about the design of LNA. I have...
Hi,
I have made a pure sine wave 3 phase power inverter but its been some time. I dont have the exact values with me right now but I'm sure if you use following formulas you will get good results. Try it in proteus first.
If you need more power than make sure you get high ampere rating...
Hello,
I made 3 phase pure sine wave inverter as my FYP a few years back. Use the following formulas:-
If more power is needed than make sure you get high amperes rating inductors.
Good Luck!
Hi all,
I'm working on a 3 phase inverter and for that I have generated 3 PWMs from PIC16F1787. Now I'm stuck at giving them a phase difference. Can anyone help me in this matter? See attached Picture for what I want exactly.
Thanks in Advance
