LNA3030

LNA3030 is an in-line SMA Low Noise Amplifier with SAW filter.

hardware notes

Schematic and layout files were designed in KiCad, an open source electronic design automation package.

This design may be assembled with any SAW filter with a standard 3.0 x 3.0 mm footprint (DCC6C).

The PCB is designed to fit the Crystek SMA-KIT-1.5MF housing.
