Description

GA30 - DV is the latest launch of the single stage of the low noise amplifier, its technical characteristics are as follows:

1. Digital display gain: LED digital display, clearly display the current amplifier gain;

2. Touch-tone gain adjustment: through the upper and lower key, you can adjust the gain when needed;

3. Power control: toggle the power switch, easy control power supply state ;

Covers the GPS, Galileo, and GLONASS, Beidou 2 etc. The device features 30dB gain and a noise figure less than 3dB. Since the product consumes less than 20mA, the device can be placed in line with the receiver antenna and can be powered by the GPS receiver's antenna voltage output.

The GA30-DV is More practical than any competitive product in the market.
