RF Micro Devices RF2413
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. 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.
