General Description
The HMC467LP3 & HMC467LP3E are broadband
2-bit GaAs IC digital attenuators in low cost leadless
surface mount packages. Covering DC to 6.0 GHz, the
insertion loss is less than 0.7 dB typical. The attenuator
bit values are 2 (LSB) and 4 dB for a total attenuation
of 6 dB. Attenuation accuracy is excellent at ± 0.2 dB
typical step error with an IIP3 of +50 dBm. Two control
voltage inputs, toggled between 0 and +5V, are used
to select each attenuation state. A single Vdd bias of
+5V is required.
