GVA-81+

Overview

The GVA-81+ is a wideband monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates from DC to 6 GHz and provides a nominal gain of 8.1 dB. The device features a noise figure of 8.3 dB, a P1dB compression point of 17.7 dBm, and an OIP3 of 31.1 dBm. It requires a 5 V supply voltage with a typical operating current of 103 mA. The component is housed in a surface-mount SOT-89-4 package and is RoHS compliant.

Feature Summary

• Wideband operation covering DC to 6 GHz frequency range
• High dynamic range performance with repeatable lot-to-lot consistency
• SMT MMIC construction using HBT technology for low phase noise
• RoHS compliant design with SnAgNi lead finish

Applications

• CATV systems
• DBS receivers
• LTE infrastructure
• Wireless LAN applications

Procurement Notes

Verify the specific datasheet version and manufacturer documentation before integration. Confirm that the SOT-89-4 package dimensions and thermal characteristics align with your PCB layout requirements. Ensure the 5 V supply voltage and 103 mA current draw are supported by your power management design. Check for any regional compliance certifications required for your target market.

Selection Notes

Select this component when a linear, medium-power amplifier is needed for broadband applications up to 6 GHz. The 8.1 dB gain and 17.7 dBm P1dB make it suitable for driving subsequent stages without significant distortion. Consider the SOT-89-4 package size if space constraints exist. Evaluate the 8.3 dB noise figure against system sensitivity requirements.

Part Context

The GVA-81+ belongs to Mini-Circuits' GVA series of RF amplifiers. These components are designed as general-purpose, linear amplifiers for RF and IF applications. The series typically offers consistent performance across manufacturing lots, ensuring reliability in mass production environments. The GVA-81+ specifically targets applications requiring moderate gain and high linearity within a compact surface-mount footprint.
