ADF7021-NBCPZ-RL

RF Transceiver ICS Overview

The ADF7021-NBCPZ-RL is a high-performance, low-power narrow-band transceiver IC designed for sub-GHz applications. It operates within frequency ranges of 80 MHz to 650 MHz and 842 MHz to 916 MHz, supporting data rates up to 24 kbps. The device features IF filter bandwidths of 9 kHz, 13.5 kHz, and 18.5 kHz, ensuring compliance with global narrowband standards requiring 12.5 kHz channel separation. Key electrical parameters include a maximum output power of 13 dBm, sensitivity of -130 dBm, receive current of 17.5 mA, and transmit current of 13.5 mA. It supports SPI and UART interfaces and functions on a supply voltage range of 2.3 V to 3.6 V.

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing components. Confirm that the operating temperature range aligns with system requirements, typically spanning -40°C to +85°C. Ensure interface compatibility with host controllers via SPI or UART protocols. Check for RoHS compliance status and moisture sensitivity levels prior to assembly planning.

RF Transceiver ICS Selection Notes

Select this component for designs prioritizing low power consumption alongside high sensitivity in licensed and unlicensed ISM bands. The integrated nature reduces external component count, benefiting cost-sensitive and area-constrained projects. Consider the available IF filter bandwidths to match specific channel spacing requirements, particularly for 12.5 kHz separation standards.

RF Transceiver ICS Part Context

This part belongs to the ADF7021 series, which includes variants like the ADF7021 and ADF7021-N. The ADF7021-N variant specifically enhances performance with narrower IF filter bandwidths compared to the base model. Evaluation boards such as EVAL-ADF7021DBZ2 are available for development support.

RF Transceiver ICS Replacement Considerations

The ADF7021-NBCPZ is a non-reel equivalent package option. Other family members include the ADF7021BCPZ and ADF7021BCPZ-RL, though these may differ in frequency coverage or specific feature sets. Verify pinout and functional equivalence before substitution.
