Overview
The HMC346ALP3ETR is an absorptive Voltage Variable Attenuator (VVA) produced by Analog Devices Inc. This component operates over a wide frequency range from DC to 14 GHz and is packaged in a low-cost leadless surface mount plastic package. It features an on-chip reference attenuator, enabling simple single voltage attenuation control using an external op-amp. The device is designed for applications where an analog DC control signal must control RF signal levels over a 30 dB amplitude range.
