MAX41470GTC+T

RF Receivers Overview

The MAX41470GTC+T is a high-performance, low-power RF receiver designed for Sub-1GHz ISM band applications. It supports Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Gaussian FSK (GFSK) modulation schemes. The device operates within a frequency range of 290 MHz to 960 MHz and features an SPI interface for configuration. It provides a sensitivity of -127 dBm and supports data rates up to 200 Kbps. The component functions on a supply voltage ranging from 1.8 V to 3.6 V and is housed in a 12-TQFN package.

RF Receivers Procurement Notes

Verify the specific suffix 'GTC' corresponds to the 12-TQFN package and temperature range requirements. Confirm that the '+T' designation indicates tape and reel packaging if required by automated assembly processes. Ensure compatibility with the host microcontroller's SPI protocol settings. Validate that the operating voltage range aligns with the system power supply design.

RF Receivers Selection Notes

Select this component when a low-cost, low-power receiver is needed for Sub-1GHz ISM bands. It is appropriate for applications requiring simple modulation schemes like ASK or FSK. Consider the 12-TQFN footprint for space-constrained designs. Evaluate the -127 dBm sensitivity against link budget requirements. Compare with I2C variants if bus interface preferences differ.

RF Receivers Part Context

The MAX41470 belongs to the MAX4147X family of Sub-1GHz ISM receivers manufactured by Analog Devices/Maxim Integrated. This series includes variants with different interfaces, such as the MAX41473 which utilizes an I2C interface instead of SPI. The family targets cost-sensitive wireless applications requiring robust performance in the license-free ISM spectrum.

RF Receivers Replacement Considerations

The MAX41473GTC+ is a functional alternative offering identical RF performance but utilizes an I2C interface instead of SPI. Designers must verify software compatibility when switching between these variants due to the interface difference.
