Low-Cost, 315MHz, 345MHz, and 433.92MHz  
ASK Transceiver with Fractional-N PLL  
MAX730  
General Description  
Features  
The MAX7030 crystal-based, fractional-N transceiver is  
designed to transmit and receive ASK/OOK data at fac-  
tory-preset carrier frequencies of 315MHz, 345MHz†, or  
433.92MHz with data rates up to 33kbps (Manchester  
encoded) or 66kbps (NRZ encoded). This device gen-  
erates 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.  
o +2.1V to +3.6V or +4.5V to +5.5V Single-Supply  
Operation  
o Single-Crystal Transceiver  
o Factory-Preset Frequency (No Serial Interface  
Required)  
o ASK/OOK Modulation  
o +10dBm Output Power into 50Ω Load  
o Integrated TX/RX Switch  
o Integrated Transmit and Receive PLL, VCO, and  
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 inte-  
ger-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.
