BROADBAND DUAL-CONVERSION

QUADRATURE MODULATOR

Product Description

The RF2412 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 100MHz to 1000MHz. The IC contains all of the

required components to implement the modulation func-

tion including differential amplifiers for the baseband

inputs, a LO 90擄 hybrid phase splitter, limiting LO amplifi-

ers, two balanced mixers, a combining differential ampli-

fier, a second upconvert balanced mixer, and an output

RF amplifier which will drive a 50鈩?load. Since the modu-

lation is performed at a low frequency, excellent ampli-

tude balance and phase accuracy are obtained.
