I'm looking to construct a very low wattage amplifier for some biotech research. I was hoping someone on here would have some pointers for constructing such a device as the cost from the companies who make low wattage amplifiers doesn't fit our startup budget (we have more time than money it seems!).
My background is software and my partner's background is chemical engineering with some wafer fab experience in the 50s and 60s, so we can probably figure things out if we get pointed at the right parts to bang our heads on.
Thank you in advance!
Here is a diagram that describes the inputs and outputs, the cyan box is the ideal wide band amplifier, and the yellow boxes would be less ideal selectable frequency or completely separate amps that support those frequencies.
And here it is in text as well:
Input:
10 V RMS & 3mA input
Sine wave
50 OHMS impedance match
300 kHz to 3.3 MHz
Output:
50 V RMS
Sine wave
50 OHMS impedance match
15 mA
wide band 300 kHz to 3.3 MHz
OR separate amps that will output the following frequencies
300 kHz
1.6 MHz
3.0 MHz
3.3 MHz
