rfid 13.56 class e amplifier
The project is my own. I wish i had the use of a network analyzer. It would makes things that much easier. So i don't know the impedance of the antenna but the transmitter data sheet list two things;
- load impedance at the Transmitter is 10 ohms
- Transmit...
uh of rfid inductance 13.56mhz
humm. i was thinking of using a spectrum analzyer, which can detect 13.56mhz frequency. Use a pi-network to impedance matching of the transmitter to the antenna. the only problem is with the pi-network I dunno what values to start with... should they be variable...
amplifier 13.56mhz rfid by power amp
the bypass cap is used to kill off the AC going back to the supply ? i'll give that a try. I'll have to check and see if i can get a FM receiver for 13.56mhz.
thanks.
so i have made a copper tube antenna that has dimensions of 1m x 1m with a thickness of an inch. The antenna is tuned for 13.56Mhz i know it works because i used a spectrum analyzer and it detects the antenna. What i want to know is. with this antenna design, am i able to achieve a 1 meter read...
13.56 mhz hf antenna amplifier
Nope. The schematic above is exactly what I built
Added after 1 hours 12 minutes:
Hey all. I'm a little stumped on how to perform impedance matching between the antenna and the amplifier. The antenna i built was built to spec and had an impedance of 50 ohms...
13.56mhz power amp
okay. i built that amp on PCB and it works... but i'm not getting the desired gain i need. I'm thinking that i need to design a different, smaller antenna for this to work. i'll look into inductive coupler as mentioned.
13.56 mhz receiver
Hi all. I wish I had found this forum a little sooner.
I'm trying to design a RF power amplifier to work at 13.56Mhz. I'm trying to amplify the transmit power from a Texas Instrument TRF7960 reader IC. I want an output power of 8 Watts to power up an antenna that I have...
