TQP4M9072
High Linearity 6-Bit, 31.5 dB Digital Step Attenuator
Typical Performance Plots
Performance plots data is measured using Bias Tee on RF ports in Mode 2 configuration. Mode 2 operation is
required to obtain performance at frequencies lower than 0.7 GHz. For frequency range 0.7 – 4.0 GHz, data is
identical in Mode 1 and Mode 2.
