915MHz ISM Applications
The RF2909 is a monolithic integrated transmitter IC
capable of universal direct modulation. The quadrature
modulator allows for a variety of modulation formats and
compound carriers. The transmitter has two power control
modes. Two inputs can be controlled digitally for stepping
output power 1mW, 10mW, or 70mW output power. Or,
the output level can be adjusted by an analog input from
1mW to 80mW. The quadrature mixers have differential
inputs, and are internally biased; a DC blocking capacitor
is required if external DC levels are present. The LO is
split with a passive network tuned for 915MHz.
