MAX7031HATJ17

RF Transceiver ICS Overview

The MAX7031HATJ17 is a crystal-based, fractional-N transceiver designed for FSK data transmission and reception at factory-preset carrier frequencies of 308MHz, 315MHz, or 433.92MHz. It supports data rates up to 66kbps with NRZ encoding or 33kbps with Manchester encoding. The device generates +10dBm output power into a 50Ω load and exhibits typical sensitivity of -110dBm. Operating on a single supply of +2.1V to +3.6V or +4.5V to +5.5V, it features integrated TX/RX switching, PLLs, and VCOs. Current consumption is less than 12.5mA in transmit mode, less than 6.7mA in receive mode, and less than 800nA in shutdown.

RF Transceiver ICS Feature Summary

• Factory-preset frequency operation eliminates the need for serial interfaces
• Integrated RF switch connects transmit and receive pins to a common antenna
• Fast-on startup feature enables rapid activation in under 250µs
• RSSI output provides high dynamic range signal strength indication

RF Transceiver ICS Applications

• General-purpose ISM band applications below 1GHz
• Wireless sensor networks requiring low-power FSK communication
• Remote control systems utilizing preset carrier frequencies

RF Transceiver ICS Procurement Notes

Verify the specific suffix '17' against official Maxim Integrated documentation to confirm the exact factory-preset frequency variant (308MHz, 315MHz, or 433.92MHz). Ensure the package type matches the required 32-pin Thin QFN form factor. Confirm that the operating voltage range aligns with the system's single-supply requirements before integration.

RF Transceiver ICS Selection Notes

Select this component when fixed-frequency FSK modulation is required without programmable frequency synthesis overhead. It is suitable for designs needing high image rejection greater than 45dB and low current consumption. Consider the integrated TX/RX switch if board space constraints prevent external switching components.

RF Transceiver ICS Part Context

This part belongs to the MAX7031 family of low-cost, crystal-based fractional-N transceivers. The HATJ17 designation specifies the industrial temperature grade, thin QFN packaging, and specific factory-set operational parameters defined by Maxim Integrated for general-purpose ISM band applications.

RF Transceiver ICS Replacement Considerations

Consult Analog Devices official substitution guides for cross-reference options. Verify compatibility regarding pinout, electrical characteristics, and thermal performance before replacing existing inventory.
