TRF372017 300MHz to 4.8GHz Quadrature Modulator

Texas Instruments TRF372017 300MHz to 4.8GHz Quadrature Modulator is a high performance direct up-conversion device, integrating a high linearity, low noise IQ modulator and an integer-fractional PLL/VCO. The VCO uses integrated frequency dividers to achieve a wide, continuous tuning range of 300MHz-4800MHz. The LO is available as an output with independent frequency dividers. TI TRF372017 Quadrature Modulator also accepts input from an external LO or VCO. The modulator baseband inputs can be biased either internally or externally. Internal DC offset adjustment enables carrier cancellation. This TI device is controlled through a 3-wire serial programming interface (SPI). A control pin invokes power-save mode to reduce power consumption while keeping the VCO locked for fast startup.
