General Description
The HMC346LC3B is an absorptive Voltage Variable
Attenuator (VVA) in a leadless 鈥淧b free鈥?RoHS compli-
ant SMT mount plastic 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.
