BHWM257-EVB

RF Front End (LNA + PA) Overview

The BHWM257-EVB is an evaluation board for the BHWM257 RF front-end module, designed for 2.4 GHz to 2.5 GHz ISM band applications. It integrates a Low Noise Amplifier (LNA) and Power Amplifier (PA) to support IEEE 802.15.4, Bluetooth, and Zigbee protocols. The underlying component utilizes an 8-DFN (2x2 mm) package. Key electrical specifications include a maximum operating frequency of 2.5 GHz and a minimum frequency of 2.4 GHz. The PA delivers 13 dBm output power with a corresponding current consumption of 22 mA at this power level.

RF Front End (LNA + PA) Feature Summary

• Integrates LNA and PA functions within a single compact RF front-end solution
• Optimized for low-power IoT wireless communication standards
• Supports standard 2.4 GHz ISM band operation

RF Front End (LNA + PA) Applications

• Evaluation of 802.15.4 compliant wireless sensor networks
• Testing Bluetooth Low Energy (BLE) connectivity performance
• Validation of Zigbee protocol stack integration

RF Front End (LNA + PA) Procurement Notes

Verify that the specific order corresponds to the BHWM257-EVB evaluation kit rather than the standalone BHWM257 component. Confirm that the package includes necessary accessories such as USB cables and antennas if required for immediate testing. Ensure compatibility with the target host microcontroller or SoC before deployment.

RF Front End (LNA + PA) Selection Notes

Select this evaluation board when validating the performance of the BHWM257 module in a complete system context. It is suitable for engineers requiring a reference design to assess signal integrity, power consumption, and range capabilities for 2.4 GHz IoT devices prior to final PCB layout.

RF Front End (LNA + PA) Part Context

This evaluation board serves as a development tool for the BHWM257, an RF front-end IC manufactured by BHW Technologies. The BHWM257 itself is a discrete component housed in an 8-DFN package, intended for integration into compact wireless modules. The EVB facilitates rapid prototyping and characterization of the amplifier's gain, noise figure, and linearity characteristics.

RF Front End (LNA + PA) Replacement Considerations

No public confirmed substitute part numbers are available for this specific evaluation kit. For component-level replacement, consult official cross-reference data for the BHWM257 IC.
