LVA-123+

Overview

The LVA-123+ is a monolithic microwave integrated circuit (MMIC) wideband amplifier manufactured by Mini-Circuits. It operates within a frequency range of 10MHz to 12GHz, suitable for LTE, MMDS, and Wireless LAN applications. The device features a gain of 8.1dB, a noise figure of 5.9dB, and a P1dB output power of 17.2dBm. It requires a supply voltage of 4.8V to 5.2V with a typical current consumption of 52mA. The component is housed in an 8-VQFN package with dimensions of 3x3mm and includes a bare pad for thermal management.

Feature Summary

• Provides high dynamic range performance across a wide bandwidth from 10MHz to 12GHz
• Designed as a gain block amplifier for signal amplification in RF systems
• Utilizes a compact surface-mount QFN package for efficient PCB integration

Applications

• Test and measurement equipment
• LTE communication systems
• Wireless LAN infrastructure

Procurement Notes

Verify the specific ordering suffix when purchasing, such as TR for tape and reel or CT for cut tape, to ensure compatibility with automated assembly processes. Confirm that the component meets RoHS3 compliance standards required for your manufacturing environment. Check the datasheet for the correct pinout configuration and thermal pad connection requirements to ensure proper electrical grounding and heat dissipation during operation.

Selection Notes

Select this component when a wideband amplification solution is required up to 12GHz with moderate gain specifications. Consider the 5.9dB noise figure and 17.2dBm linear output power limits against system link budget requirements. Ensure the 52mA supply current fits within the power constraints of the target application. Evaluate the 8-QFN package size against available board space and thermal design capabilities.

Part Context

The LVA-123+ belongs to the LVA series of MMIC wideband amplifiers from Mini-Circuits. This family is characterized by high dynamic range and consistent performance across broad frequency spans. These components are typically used as gain blocks in RF front-ends where stable amplification over a wide spectrum is necessary without significant variation in gain or noise characteristics.

Replacement Considerations

Consult official Mini-Circuits documentation for direct cross-reference part numbers. Verify that any substitute component matches the 10MHz to 12GHz frequency range, 8.1dB gain, and 8-VQFN package footprint to maintain system integrity.
