MAXIM MAX7030 handbook
MAX7030 is a radio frequency transceiver manufactured by Texas Instruments. It has a 16-bit fractional N phase-locked loop (PLL), works at 315MHz, 345MHz or 433.92MHz, supports ASK/OOK modulation with bandwidth up to 33kbps (Manchester encoded) or 66kbps (NRZ encoded). The device has a typical output power of +10dBm into a 50Ω load and exhibits a typical sensitivity of -114dBm. MAX7030 has 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. MAX7030 transmit frequency is generated by a 16-bit fractional-N 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. MAX7030 is available in a small, 5mm x 5mm, 32-pin thin QFN package, and is specified to operate over the automotive -40°C to +125°C temperature range.
