Functional Diagram

General Description

The HMC473MS8 & HMC473MS8E are general

purpose absorptive voltage variable attenuators

in 8-lead MSOP packages. The devices operate

with a +3.3V supply voltage and a 0 to +3V control

voltage. Unique features include a high dynamic

attenuation range of up to 48 dB and excellent

power handling performance through all attenuation

states. The HMC473MS8 & HMC473MS8E are ideal

for operation in wireless applications from 0.45 to

1.6 GHz. Operation from 1.7 to 2.2 GHz is possible

with a reduced maximum attenuation of 29 to 32 dB.

Improved control voltage linearity vs. attenuation can

be achieved with an external driver circuit.
