HMC802LP3E v00.0110 20 dB GaAs MMIC 1-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 10 GHz Attenuators - DIGITAL - SMT 5 Typical Applications Features The HMC802LP3E is ideal for both RF and IF applications: Low Insertion Loss: 3 dB • Test Equipment and Sensors High IP3: +55 dBm • ISM, MMDS, WLAN, WiMAX, WiBro Single Control Line • Microwave Radio & VSAT TTL/CMOS Compatible Control • Cellular Infrastructure Single +5V Supply ± 0.6 dB Typical Step Error 16 Lead 3x3mm SMT Package: 9mm² Functional Diagram General Description The HMC802LP3E is a broadband bidirectional 1-bit GaAs IC digital attenuator in a low cost leadless surface mount package. This single positive control line digital attenuator utilizes off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 10 GHz, the insertion loss is less than 3 dB typical and attenuation accuracy is excellent at ±0.6 dB typical. The attenuator also features a high IIP3 of +55 dBm. One TTL/CMOS control input is used to select the attenuation state and a single Vdd bias of +5V is required.
