HMC801LP3E v01.0610 15 dB GaAs MMIC 1-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 10 GHz 5 Typical Applications Features the HMC801LP3e is ideal for both rF ± 0.4 dB typical step error t and IF applications: M Low Insertion Loss: 2 dB •test equipment and sensors s High IP3: +53 dBm - •IsM, MMDs, WLAn, WiMAX, WiBro single Control Line E L •Microwave radio & VsAt ttL/CMos Compatible Control A t •Cellular Infrastructure single +5V supply T GI 16 Lead 3x3 mm sMt Package: 9 mm² I D Functional Diagram General Description E - the HMC801LP3e is a broadband bidirectional 1-bit s GaAs IC digital attenuator in a low cost leadless sur- r face mount package. this single positive control line o L digital attenuator utilizes off chip AC ground capaci- t A tors for near DC operation, making it suitable for a u wide variety of rF and IF applications. Covering DC O n to 10 GHz, the insertion loss is less than 2 dB typical e and attenuation accuracy is excellent at ±0.4 dB typi- t cal step error. the attenuator also features a high IIP3 t of +53 dBm. one ttL/CMos control input is used to A S select the attenuation state and a single Vdd bias of +5V is required.
