HMC306AMS10 / 306AMS10E v00.1113 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.7 - 3.8 GHz Typical Applications The HMC306AMS10 / 306AMS10E is ideal for: • Cellular; UMTS/3G Infrastructure • ISM, MMDS, WLAN, WiMAX • Microwave Radio & VSAT • Test Equipment and Sensors Features RoHS-Compliant Product 0.5 dB LSB Steps to 15.5 dB Single Positive Control Per Bit ± 0.2 dB Typical Bit Error Miniature 15 mm2 Package: MSOP10 Functional Diagram General Description The HMC306AMS10 & HMC306AMS10E are general purpose broadband 5-bit positive control GaAs IC digital attenuators in 10 lead MSOP surface mount plastic packages. Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2.3 dB. These attenuators’ bit values are 0.5 (LSB), 1, 2, 4 and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ± 0.2 dB typical with an IIP3 of up to +52 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is requ- ired. Electrical Specifications, TA = +25° C, Vdd= +3V to +5V & VCTL= 0/Vdd (Unless Otherwise Stated) Parameter Insertion Loss Attenuation Range Return Loss (RF1 & RF2, All Atten.

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. Evaluation Circuit Board * R2 - R6= 100 Ohm. These resistors are optional and may be used to enhance decoupling of the RF path from the control inputs.

Signal lines should have 50 Ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
