RFID reader Amplifier
Hi! i've been looking for a amplifier/power amplifer for an RFID reader.
the operating frequency of the reader is 13.56MHz and the modulation is
Ampitude Shift Keying (ASK). i've been researching for almost a month
and i cant find the appropriate amplifier, nor a clear computation or
circuit that is when using transistors.
Another problem i have is that...is it ok to use a power amplifier and not
an RF power amplifer to do amplify the output signal of the RFID reader?
i can't find a transistor that operates at the HF band...common RF transistors are labeled for VHF and UHF only.
I also tried to implement RF op amp but i don't know to implement it
correctly and i can't find the correct amplifier that can amplify a voltage to
a higher voltage (for instance 20V) or to a higher power (4W)
Hoping for your help, thank you in advance
