General Description
The HMC467LP3 & HMC467LP3E are broadband
2-bit GaAs IC digital attenuators in low cost leadless
surface mount packagesꢀ Covering DC to 6ꢀ0 GHz, the
insertion loss is less than 0ꢀ7 dB typicalꢀ The attenuator
bit values are 2 (LSB) and 4 dB for a total attenuation
of 6 dBꢀ Attenuation accuracy is excellent at 0ꢀ2 dB
typical step error with an IIP3 of +50 dBmꢀ Two control
voltage inputs, toggled between 0 and +5V, are used
to select each attenuation stateꢀ A single Vdd bias of
+5V is requiredꢀ
Electrical Specifications, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V*
