RF Transceiver Modules And Modems Procurement Notes

Verify that the specific suffix 'I' denotes the industrial temperature grade (-40°C to +85°C), distinct from commercial variants. Confirm the presence of the integrated PCB antenna and shielded enclosure matches the design requirements. Ensure the host system provides the necessary 1.9 V to 3.6 V supply rail and interfaces such as SPI, UART, or I2C for proper communication.

RF Transceiver Modules And Modems Selection Notes

Select this component when industrial-grade reliability and multiprotocol support are required in a compact form factor. It is suitable for designs needing pre-certified RF solutions to reduce development time. Consider the 1 MB flash capacity for complex protocol stacks. Verify compatibility with the host MCU's voltage levels and interface capabilities before integration.

RF Transceiver Modules And Modems Part Context

This module belongs to the WBZ45 series, which pairs the PIC32CX-BZ2 wireless MCU with RF front-end components. It serves as a complete solution for developers seeking to implement BLE and 802.15.4 connectivity without designing custom RF circuits. The series offers various packaging and antenna options to suit different product constraints.

RF Transceiver Modules And Modems Replacement Considerations

The WBZ451PE-E is a commercial-grade variant with an extended temperature range up to +125°C. Ensure the application environment does not require the higher thermal limits of the E-series if selecting the I-series.
