Typical Applications

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.

The HMC273AMS10G(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 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 Analog Devices, upon request.
