v02.1100 MICROWAVE CORPORATION HMC273MS10G 1 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.7 - 3.7 GHz Features 1 dB LSB Steps to 31 dB Single Positive Control Per BIT +/- 0.5 dB Typical Bit Error Miniature MSOP 10 Package: 14.8mm2 Typical Applications The HMC273MS10G is ideal for: 9 ATTENUATORS - SMT • Cellular • PCS, ISM, MMDS • WLL applications Functional Diagram General Description The HMC273MS10G is a broadband 5 - bit positive control GaAs IC digital attenuator in a 10 lead MSOP plastic package. Covering 0.7 to 3.7 GHz, the insertion loss is typically less than 2 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 ± 0.5 dB typical with an IIP3 of up to +48 dBm. Five bit control voltage 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.

These resistors are optional and may be used to enhance decoupling of the RF path from the control inputs. The circuit board used in the final 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.
