Low Noise Amplifier module based on the PGA-103+, covering 20MHz to 3GHz.

Includes:
Input overload protection diode (BAV99)
5-16 V DC supply range with reverse polarity protection
Apply 5 V DC directly to J3, or 8-16 V DC to J4
On-board Low Drop 5 V voltage regulator
Jumper to select between direct 5 V DC or regulated power
Bias-T on the output, compatible with both 5 V and 12 V supply
PCB dimensions: 63×28 mm
