Overview

• CDMA Systems • General Purpose Frequency Conversion • Portable Battery Powered Equipment RF2413 • Digital and Spread Spectrum Systems • Analog Communication Systems • GSM Systems The RF2413 is a monolithic integrated transmitter universal 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 and 1000MHz.
Up to 60dB 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 amplifier which will drive a 50 Ω load.
