HMC346LC3B
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 HMC346LC3B 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 -3V.
The device is ideal in designs where an analog DC
control signal must control RF signal levels over a
30 dB amplitude range. The HMC346LC3B allows
the use of surface mount manufacturing techniques.
