GPS Networking VATTENDCB Variable Attenuator DC Block
This Variable Attenuator DC Block (VATTENDCB) from GPS Networking is a one input, one output attenuator that operates with a variable attenuation range that can be user selected via a potentiometer control. This unit provides between 3 – 37dB (typical) of attenuation in a miniaturized housing. The frequency response covers the GPS L1/L2 and GLONASS bands with excellent flatness. In the normal configuration, the RF output (j1) accepts DC voltage from the connected GPS receiver to power the attenuator while the antenna input (ANT) is DC blocked.
