We need a custom schematic design ready for layout, which can implement an RMS level to DC level converter for detecting a signal amplitude with an A/D converter.
Input frequency: 1 Hz to 500 MHz
Input range: -90 dBm to +10 dBm
Accuracy: 0.1 dBm
Board size: max 100 mm by 50 mm
Power source: USB
The device is a simple analog in, analog out detector for measuring RMS value of a small signal in the frequency range 1 Hz to 500 MHz. With the input signal applied at the input, the output should be a DC voltage in the range of 0V to about 3V for feeding into a suitable A/D converter. The A/D converter is not part of the detector, but suitable types may be suggested.

Four steps are defined for this project:
1) Schematic ready for layout
3) Functional prototype
4) Verification test
Please bid for the first step only along with individual estimates (time and money) for the remaining 3 steps.
