Electrical Speci cations,
TA = +25° C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated)
Typical Applications
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.
The HMC273MS10G(E) is ideal for:
• Cellular; UMTS/3G Infrastructure
• ISM, MMDS, WLAN, WiMAX
• Microwave Radio & VSAT
• Test Equipment and Sensors

Application Circuit
DC blocking capacitors C1 & C2 are required on RF1 & RF2. Choose C1 = C2 = 100 ~ 300 pF to allow lowest customer speci c
frequency to pass with minimal loss. R1 = 5K Ohm is required to supply voltage to the circuit through either PIN 6 or PIN 10.

Evaluation Circuit Board
The circuit board used in the nal application
should use RF circuit design techniques. Signal
lines should have 50 ohm impedance while the
package ground leads and exposed ground paddle
should be connected directly to the ground plane
similar to that shown below. A sufficient number
of via holes should be used to connect the top
and bottom ground planes. The evaluation circuit
board as shown is available from Hittite Microwave
Corporation upon request.

These resistors are optional
and may be used to enhance
