Product Description
The XXATTENDCB GPS RF Attenuator is a one input, one output device with a constant attenuation anywhere in the range from 1dB to 20dB, as specified by the customer. The device is available in a miniaturized housing. The frequency response covers the GPS L1/L2 and GLONASS bands with excellent flatness. In the DC Blocked configuration, the RF output (J1) blocks DC from the connected GPS receiver through the attenuator to the antenna.
