The MAX7033 fully integrated low-power CMOS super-heterodyne receiver is ideal for receiving amplitude shift-keyed (ASK) data in the 300MHz to 450MHz frequency range. The receiver has an RF input signal range of -114dBm to 0dBm. With few external components and a low-current power-down mode, it is ideal for cost-sensitive and power-sensitive applications typical in consumer markets. The MAX7033 consists of a low-noise amplifier (LNA), a fully differential image-rejection mixer, an on-chip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO), a 10.7MHz IF limiting amplifier stage with received-signal-strength indicator (RSSI), and analog baseband data-recovery circuitry. The MAX7033 also has a discrete one-step automatic gain control (AGC) that reduces the LNA gain by 35dB when the RF input signal exceeds -62dBm. The AGC circuitry offers an externally controlled hold feature.

The MAX7033 is available in 28-pin TSSOP and 32-pin TQFN packages and is specified over the extended (-40°C to +105°C) temperature range.

  • Product Detail

    The MAX7033 evaluation kit (EV kit) allows for a detailed evaluation of the MAX7033 superheterodyne receiver. It enables testing of the device's RF performance and requires no additional support circuitry. The RF input uses a 50Ω matching network and an SMA connector for convenient connection to test equipment. The EV kit can also directly interface to the user's embedded design for easy data decoding.

    The MAX7033 EV kit comes in two versions: 315MHz and 433.92MHz. The passive components are optimized for these frequencies. These components can easily be changed to work at RF frequencies from 300MHz to 450MHz. In addition, the received data rate can be adjusted from 0 to 66kbps by changing three more components.

    For easy implementation into the customer's design, the MAX7033 EV kit also features a proven PC board layout, which can be easily duplicated for quicker time to market. The EV kit Gerber files are available for download at www.maximintegrated.com.
