LNA60 3V3 Case 1090MHz Filter Ver-3.2

4 layer board of 3.15 x 0.89 inches (80.0 x 22.7 mm).
Shared on April 4th, 2017 03:00

Low Noise Amplifier for SDR Radio ADS-B reception Ver. 3.2 with 1090MHz ceramic-coaxial-resonator based bandpass filter, for aluminum case 25x25x80mm mount and 5 volt bias power. This board uses mostly the same components as the Ver 2.3 board linked below, but places the bandpass filter before the LNA and also requires 5VDC external bias power thru the output SMA connector. NOT-TESTED https://www.barbouri.com/2017/03/12/low-noise-amplifier-for-sdr-radio-ads-b-ver-2-3-with-1090mhz-ceramic-filter/
