HMC346ALP3E v02.0717 GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, DC - 14 GHz 8 Typical Applications Features The HMC346ALP3E is ideal for: Wide Bandwidth: DC - 14 GHz Basestation Infrastructure Low Phase Shift vs. Attenuation Fiber Optics & Broadband Telecom 30 dB Attenuation Range Microwave Radio & VSAT Simplified Voltage Control 3 x 3 x 1 mm SMT Package Military Radios, Radar, & ECM Test Instrumentation Functional Diagram General Description The HMC346ALP3E is an absorptive Voltage Variable Attenuator (VVA) in low cost leadless surface mount plastic package operating from DC - 14 GHz. It fea- tures an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -5V. The device is ideal in designs where an analog DC control signal must con- trol RF signal levels over a 30 dB amplitude range.
