Single-supply DAC controlled bidirectional current source?
To get 25mA into 20Ohm requires 0.5 Volts, so a singe 5V supply design should be possible. First generate a stable 2.5V mid-point voltage by using a opamp that can deliver 25mA....

atmega ADC sampling time
The sampling-unit inside the AVR is not as bad as it seems. So you may run the ADC at maximum speed (ADC clock=200kHz) and sample a faster Signal (I have used it up to 600kHz)....

tutorial/document/book about RF for "dummies"
Up to now the discussion was more or less in the so called time domain. Another view is provided by the frequency domain, where you look at the spectrum of a signal. The spectrum...

I found unter recommanded operation condition of LM5101 that VDD shoould be between 9 and 15 Volts. So it seems that 5V operation is not recommanded. 5V Driver would probably mean...
