General Description
The HMC273AMS10G(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 3 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 +46 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,
TA = +25° C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated)

1 dB LSB GaAs MMIC 5-BIT DIGITAL
ATTENUATOR, 0.7 - 3.8 GHz
DC blocking capacitors C1 & C2 are required on RF1 & RF2. Choose C1 = C2 = 100 ~ 300 pF to allow lowest customer specific
frequency to pass with minimal loss. R1 = 5K Ohm is required to supply voltage to the circuit through either PIN 6 or PIN 10.
