LNA
About the LNA PCB
LNA is an open source PCB design by alicjamusial, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 35 × 20 mm, with 18 components from 15 distinct parts.
Other key parts include the PGA-103+. By type, the board carries 7 capacitors, 6 inductors, 3 connectors, 1 IC and 1 resistor.
It belongs with the rf & radio and audio designs in this gallery.
From the project
LNA with filter for 400-440 MHz (UHF for amateur satellites)
Lynx is an LNA with a filter with two SMA connectors. It was designed for 400-400 MHz (UHF satellite amateur band) by default, but by changing components' values it can be tuned to every chosen frequency. It contains the amplifier (with PGA-103+ as the main component) and the bandpass Chelbyshev filter (shunt first, 2nd order).
Gerber files for version 2.0 of Lynx is available in the releases section.
