Hello everyone!
I am new here and I need an advice about this RF amplifier:
https://www.ebay.com/itm/182196835491
I purchased it with the idea to boost the signal of my RC controll which is 40 MHz.
The signal from the RC transmitter is only about 1-5 mW and the range is about 20 m.
The problem is that after looking my RF Explorer the amplifier does not work well in the 40 MHz band. It almoast does not boost the signal. I decided that the input capacitor which is about 15pF is blocking the lower frequencies so I shorted it and BOOM I get 10dB more on my RF Explorer. So it is obvious for me that the schematic can be optimised for 40 MHz.
I will be very grateful if you give me some help in my quest. What could I change to improve the performance in the 40 mhz band.
Thanks in advance guys!
