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.
