The MAX7032 is a crystal-based, fractional-N transceiver that is designed to transmit and receive ASK/OOK or FSK data in the 300MHz to 450MHz frequency range with data rates up to 33kbps (Manchester encoded) or 66kbps (NRZ encoded).
The MAX7032 is a crystal‑based, fractional‑N transceiver designed for 300 MHz to 450 MHz operation with ASK/OOK or FSK modulation. It features separate transmit and receive pins, an internal RF switch, and integrates all frequency‑generation components on‑chip, requiring only a crystal, a 10.7 MHz IF filter, and a few discrete parts.
Key specifications include typical output power of +10 dBm, ASK sensitivity of –114 dBm, FSK sensitivity of –110 dBm, supply voltage ranges of 2.1‑3.6 V (3 V mode) or 4.5‑5.5 V (5 V mode), and an automotive‑grade temperature range of –40 °C to +125 °C. The device is offered in a 5 mm × 5 mm, 32‑pin thin QFN package and consumes less than 12.5 mA in transmit mode and 6.7 mA in receive mode.
