LNA with onboard Bias tee designed for use with RTL SDR dongles. LNA has two power options, USB mini or power from dongle. There is also option for an on-board wideband bias tee and bandpass filter. See github link for eagle files.

V2 needs a resistor for the LED to operate correctly. Either the board can be redesigned or the trace between J1 and LED1 can be cut, and a resistor can be placed between the components.

PSA4-5043 – .05 to 4GHz

TCBT-14+ Bias Tee – 10MHz to 10GHz

Optional bandpass filter.
