【Descripition】
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.

Functional description:
Used to adjust system gain,0-30 dB adjustable, Accuracy for 1 dB, Error of ± 1dB .you can control when needed.
with AC220/9V power adapter, supply power to system and itself.
①②are input/output, connect to cable assembly, N female(Can be customized).
③for power control switch. system power-on and reset(Gain reset to maximum 30dB) when allocated to upward, opposite, system stops working.
④ and ⑤ button to adjust the gain level. when system installed, generally, for this device, we usually from a maximum gain gradually adjust small, we can see the SNR of the receiver begin to weak, this point of gain will be the best choose.
⑥is a LED, display the initial amplification value(level +30) when power-on .
