HMC306AMS10 / 306AMS10E v00.1113 ATTENUATORS - DIGITAL - SMT 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.7 - 3.8 GHz Typical Applications Features The HMC306AMS10 / 306AMS10E is ideal for: RoHS-Compliant Product * Cellular; UMTS/3G Infrastructure 0.5 dB LSB Steps to 15.5 dB * ISM, MMDS, WLAN, WiMAX Single Positive Control Per Bit * Microwave Radio & VSAT 0.2 dB Typical Bit Error * Test Equipment and Sensors 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 required.
