Analog Devices / Maxim Integrated MAX41473/MAX41474 RF Receivers

Analog Devices Inc. MAX41473/MAX41474 RF Receivers are high-performance and low-power devices that are ideal for Amplitude Shift-Keying (ASK) and Frequency Shift-Keying (FSK) data. The MAX41473/MAX41474 receivers are designed to receive ASK/FSK modulated data in the 287MHz to 320MHz, 425MHz to 480MHz, and 860MHz to 960MHz ISM frequency bands. These RF receivers are capable of ASK or FSK reception and are fully programmable through the I2C interface. The MAX41473/MAX41474 receivers have excellent RF sensitivity and allow input signals up to 0dBm of power at the RF input. These RF receivers come with an integrated IF filter, a few external components, and low operating/power-down currents.

ADI MAX41473/MAX41474 RF receivers feature a power-saving, fully programmable, and self-polling (duty cycling) mode with preamble detection and interrupt output to wake up an external MCU. These RF receivers operate from 1.8V to 3.6V supply voltage range and -40°C to 105°C temperature range. The MAX41473/MAX41474 RF receivers are available in 4mm x 4mm dimensions and a 12-pin thin QFN (TQFN) package with a 0.8mm pitch. Typical applications include home automation and security, building access control, Garage Door Openers (GDO), and Remote Keyless Entry (RKE).
