HMC346LP3 / 346LP3E v05.1008 GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, DC - 14 GHz 5 ATTENUATORS - SMT Typical Applications The HMC346LP3 / HMC346LP3E is ideal for: • Basestation Infrastructure • Fiber Optics & Broadband Telecom • Microwave Radio & VSAT • Military Radios, Radar, & ECM • Test Instrumentation Features Wide Bandwidth: DC - 14 GHz Low Phase Shift vs. Attenuation 30 dB Attenuation Range Simplified Voltage Control 3 x 3 x 1 mm SMT Package Functional Diagram General Description The HMC346LP3 & HMC346LP3E are pabsorptive Voltage Variable Attenuators (VVA) in low cost leadless surface mount plastic packages 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 -3V. 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.
