RF Transceiver Modules And Modems Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm the presence of the U.FL connector type in the final assembly drawings. Ensure compatibility with the host system's voltage levels, as the module requires a stable supply between 1.9 V and 3.6 V. Check for any regional regulatory certifications required for 2.4 GHz operation in the target deployment area.

RF Transceiver Modules And Modems Selection Notes

Select this module when both BLE and 802.15.4 connectivity are required on a single chip. Consider the 5 dBm output power for short-range applications. Evaluate the need for the U.FL connector versus PCB antenna options based on enclosure design. Verify that the host processor can interface via the available UART or SPI connections provided by the PIC32CX-BZ2 core.

RF Transceiver Modules And Modems Part Context

This component belongs to the WBZ45 series of multiprotocol modules from Microchip Technology. These modules combine the PIC32CX-BZ2 MCU with a certified RF transceiver. The series offers flexibility for developers needing dual-protocol support without managing separate chips. The WBZ450UE-I specifically provides the industrial temperature rating and external antenna connector option.

RF Transceiver Modules And Modems Replacement Considerations

The WBZ450UE is the commercial temperature variant of this part. The WBZ451PE-E is a newer generation module with a PCB antenna and extended temperature range. Cross-reference pinouts and firmware libraries when migrating between these specific model numbers.
