RTL-SDR Wideband LNA

This is a general purpose SPF5189Z based wideband LNA. Works from 50 MHz to 4 GHz with a noise figure of less than 1dB. Requires bias tee power, but there is an internal header which can be used to switch to external power, although for external power wires you'll need to drill a hole into the enclosure.

Requires 3 - 5v, 150mA bias tee power. The RTL-SDR V3 provides 4.5v so is suitable.
