HMC346ALC3B
GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, DC - 18 GHz
Features
Wide Bandwidth: DC - 18 GHz Low Phase Shift vs. Attenuation 30 dB Attenuation Range Simplified Voltage Control RoHS Compliant 3 x 3 mm SMT Package
General Description
The HMC346ALC3B is an absorptive Voltage Variable Attenuator (VVA) in a leadless “Pb free” RoHS compliant SMT mount ceramic package operating from DC - 18 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. The HMC346ALC3B allows the use of surface mount manufacturing techniques.
