Product Description

Glonass Low Noise Signal Amplifier Booster is a single stage gain block in a small form factor that covers the GLONASS frequencies. The device features 30 or 40dB gain and a noise figure less than 1.5dB. Since the product consumes less than 25mA, the device can be placed in line with the receiver antenna and can be powered by the receiver's antenna voltage output.

Perfect Assistant for your work

In order to avoid expensive measurements in EMC chambers, we have developed different shielding boxes. Bigger size for bigger DUT, like RC drone; Smaller size for smaller DUT, like the board. Sound isolation or signal blocking with different body material(metal sheet, aluminum sheet) and inside absorber material or different body size is against client's request. Whatever you need it, we can build it.

Shielding box full box or rf faraday cage without breaking hole design (Filter, SMA holes excluded), the frequency band is 1GHz ~ 6GHz, isolation is more than 80dB. Shielded box opened and closed is controlled by the manual button or through RS232 interface communication command. The rf shielding chamber or enclosures opens way is to take a large angle clamshell to facilitate operation. To prevent the hand grip design avoids industrial safety accident. In accordance with testing requirements can choose to use different filter interface.
