    Engineering AM-AM and AM-PM graph generation in LTSpice

    Dear Sir, Bundle of thanks for your guidance. I have followed your instruction but am still a little bit confused about drawing these graphs. I used the following commands for the simulation at first: .step param Pin -20 20 1; Sweep input power from -20 to +20 dBm .meas Vout_max MAX V(Load)...

    Engineering AM-AM and AM-PM graph generation in LTSpice

    Thank you so much, dear Sir, for your kind and prompt response. Here, I would like to inquire about one question: there is a small step phase variation in each (almost) output signal. I am a little bit confused. Why is there this variation? Is this a circuitry issue or what.........? Thanks in...

    Low Voltage level problem in STM32 system chip

    Dear all, hope you are doing great. I am designing a circuit using EasyEDA simulation tool. But I am facing a problem after connecting the relay to the single-Chip IC (STM32 103RTC6). The low voltage is showing around 2V, whereas it was originally supposed to be 0 volts. I am still unable to...

    How to enhance output Voltages of this RF Power Amplifier

    Dear Sir, Thanks for your kind reply. There is no specific requirement as you mentioned. I Just would like to enhance the voltage level at the output and output power as high as good. In some books i found they achieve the output power about 20-30W. I wish i can get too such wonderful power at...

    How to enhance output Voltages of this RF Power Amplifier

    Thanks for your prompt reply. The question you asked is quite interesting for me as well. Because I tried to calculate the output impedance of MOSFET, but unable to find exactly impedance. According to the datasheet the output impedance f IRF510 is 0.4 ohm. The output impedance seen by the FET...
