General Description
The HMC424AG16 is a broadband 6-bit GaAs IC
digital attenuator in a 16 lead glass/metal (hermetic)
surface mount package. Covering DC to 3 GHz, the
insertion loss is less than 3 dB typical. The attenuator
bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a
total attenuation of 31.5 dB. Attenuation accuracy
is excellent at ±0.5 dB typical step error with an IIP3
of +34 dBm. Six control voltage inputs, toggled bet-
ween 0 and -5V, are used to select each attenuation
state at less than 70 µA each. A single Vee bias of
-5V allows operation at frequencies down to DC.
Electrical Specifications, TA = +25° C, With Vee = -5V & Vctl = 0/-5V

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and package bottom should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Analog Devices upon request.
