The MAX1471 low-power, CMOS, superheterodyne, RF dual-channel receiver is designed to receive both amplitude-shift-keyed (ASK) and frequency-shift-keyed (FSK) data without reconfiguring the device or introducing any time delay normally associated with changing modulation schemes. The MAX1471 requires few external components to realize a complete wireless RF digital data receiver for the 300MHz to 450MHz ISM bands.

The MAX1471 includes all the active components required in a superheterodyne receiver including: a low-noise amplifier (LNA), an image-reject (IR) mixer, a fully integrated phase-locked loop (PLL), local oscillator (LO), 10.7MHz IF limiting amplifier with received-signal-strength indicator (RSSI), low-noise FM demodulator, and a 3V voltage regulator. Differential peak-detecting data demodulators are included for both the FSK and ASK analog baseband data recovery. The MAX1471 includes a discontinuous receive (DRX) mode for low-power operation, which is configured through a serial interface bus.

The MAX1471 is available in a 32-pin thin QFN package and is specified over the automotive -40°C to +125°C temperature range.

Product Detail

The MAX1471 evaluation kit (EV kit) simplifies evaluation of the MAX1471, a low power, superheterodyne, sub-GHz RF dual-channel receiver designed to receive both amplitude shift keying (ASK) and frequency-shift keying (FSK) data without reconfiguring the device in the 300MHz to 450MHz frequency range.

The MAX1471 evaluation kit operates in conjunction with an external microcontroller (MCU) and graphical user interface (GUI) software running on a computer. The MAX1471 uses an SPI interface for internal register configurations and control.

The MAX1471 EV kit is available in two versions: 315MHz (MAX1471EVKIT-315) and 433.92MHz (MAX1471EVKIT-433). The passive components are optimized for these two frequencies but can easily be changed to work at any RF frequency between 300MHz and 450MHz.

The EV kit includes Windows® 10-compatible software that provides a simple GUI for configuration of the MAX1471 registers through the SPI port. The GUI also controls the on-board PMIC and provides a quick start register configuration to evaluate the MAX1471 functionality, when the MAX32630FTHR applications platform is used.

  • Garage Door Openers
