General Description

Functional Diagram

The HMC230MS8 is a broadband 3 - bit positive

control GaAs IC digital attenuator in an 8 lead MSOP

surface mount plastic package. Covering 0.75 to

2 GHz, the insertion loss is typically less than 2

dB. The attenuator bit values are 4 (LSB), 8, and

16 dB for a total attenuation of 28 dB. Accuracy is

excellent at ± 0.5 dB typical with an IIP3 of up to

+48 dBm. Three bit control voltage inputs, toggled

between 0 and +3 to +5 volts, are used to select

each attenuation state at less than 50 uA each. A

single Vdd bias of +3 to +5 volts applied through an

external 5K Ohm resistor is required.

Electrical Speciﬁcations,

T_A= +25° C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated)
