The MAX7060 frequency and power-programmable
ASK/FSK transmitter operates at 280MHz to 450MHz
frequencies. This device incorporates a fully integrated
fractional-N synthesizer, which allows the user to set the
RF operating frequency to a large fraction of the 280MHz
to 450MHz frequency range with a single crystal. For
example, the MAX7060 can be tuned from 285MHz to
420MHz with a 15MHz crystal. The RF output power is
user-controlled between +14dBm and -14dBm, with a
5V supply or with battery voltages as low as 3.2V. At the
minimum specified battery voltage of 2.1V, the RF output
power-control range is between +10dBm and -14dBm.
To maintain a good output power match across a broad
range of frequencies, the MAX7060 also contains a programmable
matching capacitor connected in parallel
with the power amplifier (PA) output.
