GPS Source’s AT11T is a fixed attenuator RF unit that has one input and one output. It is manufactured particularly for use in accessing all GNSS L-Band channels, such as Galileo, GLONASS, GPS, and QZSS.
Users can specify the attenuation from 2 to 40 dB. The AT11T also provides the ability to pass LNA DC bias voltage through the device to the receive antenna. Alternatively, it can block the antenna’s DC path.
Due to the fixed attenuation of the AT11T, typical use is taking the reduced input level to a GPS test set or receiver. GPS Source offers a host of connection, housing, and port options for this product.
