APD Receiver

Assembly

The detection chain: an avalanche photodiode with a regulated high-voltage bias multiplies the picowatt backscatter signal, followed by a transimpedance amplifier, variable-gain stage, and sampling ADC. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
