HMC346ALP3E v01.0117 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 • Military Radios, Radar, & ECM 3 x 3 x 1 mm SMT Package Y Typical Applications R • Test Instrumentation 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 features 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 control RF signal levels over a 30 dB amplitude range. This VVA is an excellent alternative to the HMC121C8.
