BT-200 Bias-tee Low Noise Amplifier

The BT-200 is a wideband bias-tee RX Low Noise Amplifier that draws its current from the bladeRF 2.0 micro’s SMA connectors. The BT-200 is a compact LNA solution useful for substantially lowering the noise figure and substantially increasing dynamic range of most applications. bladeRF-cli and the libbladeRF API can be used to enable and disable the bias-tee when it is needed. Care should be taken to avoid overdrawing current when powering the bladeRF 2.0 micro from USB bus power and enabling multiple bias-tee amplifiers simultaneously. In case the power budget (print hardware in bladeRF-cli) is a concern, the bladeRF 2.0 micro can be powered by an external DC power supply.
NOTE: The BT-200 can only be plugged into the RX ports.
