The HMC346LP3 is an absorptive voltage variable attenuator (VVA) from Hittite Corporation. It operates from DC to 14 GHz and has a 30 dB attenuation range. It features a low phase shift, simplified voltage control, and a small package. It is ideal for basestation infrastructure, fiber optics and broadband telecom, microwave radio and VSAT, military radios, radar, and ECM, and test instrumentation.
The HMC346LP3 is an absorptive voltage-variable attenuator (VVA) designed for operation from DC to 14 GHz. It features an on-chip reference attenuator suitable for use with an external op-amp to provide simple single voltage attenuation control ranging from 0 to -3V. This device is ideal for applications requiring analog DC control signals to manage RF signal levels over a 30 dB amplitude range.
