First you should choose a transceiver, I recommend using o chip from Chipcon - Texas Instruments, like CC1000 or the newer and better but only in QFN package, CC1101. You will find more info on the TI site. You may also want to look at the ti-store because there is a solution for you with a uC...
Re: Ground Plane
You can have ground planes on both sides, but if you have an analog ciurcuit and a digital one on the same board it will be advised to have 2 ground planes, one for the opamp circuit and one for the uC, connected in one point close to the power supply, after the main capacitor...
a/d bit rate
Hello,
The "Analog Input Bandwidth of 500MHz Max" is related to the differential analog input stage, that has a 3-dB bandwidth that extends up to 500 MHz.
In other words, you can put a signal with frequencys up to 500 Mhz through the input stage and have a maximum 3 dB...
atmega128 problem
Heloo,
There are 2 solutions for you:
1. Redesign and use another port.
2. If you cannot redesign, then you cannot just skip the codevision wizzard and put the address of PORTF in the program because in ATMEGA128 the PORTF and DDRF addresses are above $00 to $1F range of...
