The MAX7030 crystal-based, fractional-N transceiver is designed to transmit and receive ASK/OOK data at factory-preset carrier frequencies of 315MHz or 433.92MHz with data rates up to 33kbps (Manchester encoded) or 66kbps (NRZ encoded). This device generates a typical output power of +10dBm into a 50Ω load and exhibits typical sensitivity of -114dBm. The MAX7030 features separate transmit and receive pins (PAOUT and LNAIN) and provides an internal RF switch that can be used to connect the transmit and receive pins to a common antenna.

The MAX7030 transmit frequency is generated by a 16-bit, fractional-N, phase-locked loop (PLL), while the receiver's local oscillator (LO) is generated by an integer-N PLL. This hybrid architecture eliminates the need for separate transmit and receive crystal reference oscillators because the fractional-N PLL is preset to be 10.7MHz above the receive LO. Retaining the fixed-N PLL for the receiver avoids the higher current-drain requirements of a fractional-N PLL and keeps the receiver current drain as low as possible. All frequency generation components are integrated on-chip, and only a crystal, a 10.7MHz IF filter, and a few discrete components are required to implement a complete antenna/digital data solution.

The MAX7030 is available in a small, 5mm × 5mm, 32-pin thin QFN package, and is specified to operate over the automotive -40°C to +125°C temperature range.

Product Detail

The MAX7030 evaluation kit (EV kit) allows for a detailed evaluation of the MAX7030 ASK transceiver. It enables testing of the device’s RF performance and requires no additional support circuitry. The RF input circuit is designed to work with a 50Ω source impedance RF signal generator or a 50Ω input impedance spectrum analyzer and has 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 MAX7030 EV kit comes in two versions: a 315MHz version and a 433.92MHz version. The passive components are optimized for these frequencies. The MAX7030 IC itself is available in three frequencies: 315MHz, 345MHz, and 433.92MHz. The EV kit board components can easily be changed to work at RF frequencies from 300MHz to 450MHz.

For easy implementation into the customer’s design, the MAX7030 EV kit also features a proven Printed Circuit Board (PCB) layout, which can be easily duplicated for quicker time-to-market. The PCB gerber files are available for download at www.maximintegrated.com

Applications

  • 2-Way Remote Keyless Entry
  • Garage Door Openers
  • Home Automation
  • Local Telemetry Systems
  • Remote Controls
  • Remote Sensing
  • Security Systems
