CC2590RGVRG4

RF Front End (LNA + PA) Overview

The CC2590RGVRG4 is a 2.4 GHz RF front-end module manufactured by Texas Instruments, designed for IEEE 802.15.4 and Zigbee applications. It integrates a low-noise amplifier (LNA) and a power amplifier (PA) to extend communication range in wireless sensor networks. The device operates within a supply voltage range of 2 V to 3.6 V and features a noise figure of 4.8 dB. It delivers up to +14 dBm output power and consumes 3.4 mA of operating current. The component is housed in a 16-pin VQFN package with dimensions of 4x4 mm, suitable for surface-mount installation across an industrial temperature range of -40°C to +85°C.

RF Front End (LNA + PA) Feature Summary

• Integrates both low-noise amplifier and power amplifier functions into a single compact module.
• Provides extended communication range capability for 2.4 GHz ISM band applications.
• Optimized for low-power operation in battery-driven wireless sensor network devices.

RF Front End (LNA + PA) Applications

• IEEE 802.15.4 compliant wireless sensor nodes
• Zigbee home automation and control systems
• Wireless personal area network (WPAN) range extension

RF Front End (LNA + PA) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status during procurement. Confirm that the part number matches the exact pinout and thermal pad requirements for your PCB layout. Ensure compatibility with the intended base transceiver chip, such as the CC2530 or CC2531 series, as documented in official application notes. Check for any recent lifecycle notices regarding obsolescence or replacement recommendations from the manufacturer.

RF Front End (LNA + PA) Selection Notes

Select this component when enhanced transmission distance and reception sensitivity are required beyond the capabilities of standard transceivers. It is appropriate for designs needing a unified solution for both signal boosting and amplification without external discrete components. Consider the VQFN package size constraints and thermal dissipation needs for high-output power scenarios. Validate that the operating voltage range aligns with the system's power supply architecture.

RF Front End (LNA + PA) Part Context

This part belongs to the CC2590 series of RF front-ends from Texas Instruments. It is functionally similar to the CC2591 but offers higher output power specifications. The 'G4' suffix typically denotes environmental compliance attributes. It serves as a critical peripheral for enhancing the performance of 2.4 GHz wireless microcontrollers in industrial and consumer IoT applications.

RF Front End (LNA + PA) Replacement Considerations

Public confirmed substitute part numbers include CC2590RGVR and CC2590RGVT. Verify if the 'G4' suffix variation affects mechanical or electrical parameters before substitution. Cross-reference with CC2591 variants if different power levels are acceptable.
