PVA-453-34+

Attenuators Overview

The PVA-453-34+ is an MMIC voltage variable attenuator from Mini-Circuits, operating within the 10 GHz to 45 GHz frequency range. It provides a total attenuation range of 0 dB to 51 dB using analog control voltages between -4 V and 0 V. The device utilizes GaAs pHEMT technology and features two independently controlled attenuators. It operates on a 50 Ohm system and is housed in a 16-VQFN exposed pad package.

Attenuators Feature Summary

• Dual independent attenuator channels for precise signal level control
• Absorptive design utilizing GaAs pHEMT technology
• Analog voltage control interface ranging from -4 V to 0 V

Attenuators Applications

• Microwave and millimeter-wave test and measurement equipment
• Phased array radar systems requiring dynamic gain adjustment
• Wireless communication infrastructure components

Attenuators Procurement Notes

Verify component authenticity through authorized Mini-Circuits distributors or direct manufacturer channels. Confirm that the specific suffix matches the required operational specifications. Ensure handling procedures comply with electrostatic discharge (ESD) protection standards due to the sensitive semiconductor nature of the GaAs pHEMT die. Review the official datasheet for detailed electrical characteristics prior to integration.

Attenuators Selection Notes

Select this component when high-frequency operation up to 45 GHz is required alongside continuous analog attenuation capabilities. The dual-channel architecture allows for complex signal processing tasks within a single footprint. Consider the 16-VQFN package for surface-mount assembly requirements. Evaluate thermal management needs based on the power dissipation characteristics defined in the technical documentation.
