General Description
The HMC273MS10G(E) is a general purpose
broadband 5-Bit positive control GaAs IC digital
attenuator in a 10 lead MSOP plastic package.
Covering 0.7 to 3.8 GHz, the insertion loss is typically
less than 2.5 dB. The attenuator bit values are
1 (LSB), 2, 4, 8, and 16 dB for a total attenuation
of 31 dB. Accuracy is excellent at ±0.2 dB typical
with an IIP3 of up to +48 dBm. Five bit control vol-
tage inputs, toggled between 0 and +3 to +5 volts, are
used to select each attenuation state. 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)
