I0JXX LNA Receive Preamplifiers offer high gain amplification with very low internal noise for VHF and UHF amateur band optimized devices used world-wide by experimenters and contest enthusiasts. Excellent receive-only performance at low current is achieved by these compact 12VDC units, available in two connector configurations: SMA female input and output, or Type N male input and female output.

LNA (low noise amplifiers) offer preamplification using ultra-low noise components as good or better than most receiver front ends, to preserve the capabilities of a low-noise antenna system. Typically, they do not have relays in the signal path that might introduce noise or loss. These devices can be used directly in most receive applications and may be used to build a sequencer-controlled Receive-Transmit relay system for two-way VHF or UHF communications.

I0JXX LNA Receive Preamplifiers are built with high quality components including low-loss FR4 copper clad PCBs and environmentally safe tri-chrome high-conductivity passivated aluminum chassis. View the specific device specifications on each part detail page.
