The RF2413 is a monolithic integrated transmitter univer-
sal modulation IC capable of generating modulated AM,
PM, or compound carriers in the VHF/UHF frequency
range. The modulation is performed at VHF, then the
resulting spectrum is upconverted to a frequency range
between 100 MHz and 1000MHz. Up to 60 dB of power
control is possible through the use of two gain control
pins. The IC contains all of the required components to
implement the modulation function including differential
amplifiers for the baseband inputs, a 90° hybrid phase
splitter, limiting LO amplifiers, two balanced mixers, a
combining, gain-controlled differential amplifier, a second
balanced mixer, and an output gain-controlled RF ampli-
fier which will drive a 50
Ω load.
