Hittite HMC346MS8G GaAs MMIC SMT Voltage-Variable Attenuator Datasheet
The HMC346MS8G from Hittite Microwave Corporation is an absorptive GaAs MMIC surface-mount voltage-variable attenuator operating from DC to 8 GHz. It provides a 32 dB attenuation range and uses an on-chip reference attenuator with an external op-amp for single-voltage attenuation control from 0 to -3 V.
The datasheet lists electrical specifications, typical performance curves, absolute maximum ratings, pin descriptions, and an evaluation PCB list of materials. It is intended for DC-8 GHz applications such as point-to-point radio, VSAT radio, AGC circuits, and temperature compensation of multiple gain stages.
