EVALUATION KIT AVAILABLE MAX7060 280MHz to 450MHz Programmable ASK/FSK Transmitter General Description Features The MAX7060 frequency and power-programmable S Fully Integrated, Fast Fractional-N PLL ASK/FSK transmitter operates at 280MHz to 450MHz 280MHz to 450MHz RF Frequency frequencies. This device incorporates a fully integrated Frequency Range 100% Tested at +125NC fractional-N synthesizer, which allows the user to set the < 250s Startup Time RF operating frequency to a large fraction of the 280MHz Adjustable FSK Mark and Space Frequencies to 450MHz frequency range with a single crystal. For Ultra-Clean FSK Modulation example, the MAX7060 can be tuned from 285MHz to 50kbps Manchester Data Rate ASK 420MHz with a 15MHz crystal. The RF output power is 70kbps Manchester Data Rate FSK user-controlled between +14dBm and -14dBm, with a S Programmable Power Amplifier 5V supply or with battery voltages as low as 3.2V. At the +14dBm Tx Power with 5V Supply minimum specified battery voltage of 2.1V, the RF output +10dBm Tx Power at 2.1V Supply power-control range is between +10dBm and -14dBm. 28dB Power-Control Range in 1dB Steps To maintain a good output power match across a broad S Tunable PA Matching Capacitor range of frequencies, the MAX7060 also contains a pro- S Control Through SPI or Manual Settings grammable matching capacitor connected in parallel with the power amplifier (PA) output. S Low Shutdown Current for 2.1V to 3.6V Supply 400nA Standby Current, Power-On-Reset ASK modulation is accomplished by switching the PA (POR) Active on and off, so excellent modulation (on/off) ratios are 5nA Shutdown Current, POR Inactive achieved. ASK amplitude shaping is available to reduce the width of the transmission spectrum.
