Overview
ATTENUATORS - SMT v05.
1008 5 Typical Applications The HMC346LP3 / HMC346LP3E is ideal for: • Basestation Infrastructure • Fiber Optics & Broadband Telecom • Microwave Radio & VSAT • Military Radios, Radar, & ECM • Test Instrumentation Functional Diagram HMC346LP3 / 346LP3E GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, DC - 14 GHz 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 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.
