HMC346LP3ETR

HMC346LP3 / 346LP3E v05.1008 ATTENUATORS - SMT 5 GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, DC - 14 GHz Typical Applications Features The HMC346LP3 / HMC346LP3E 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 • Test Instrumentation 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.
