Overview
The TRF372017IRGZT, produced by Texas Instruments, is a high-performance, direct up-conversion device that integrates a high-linearity, low-noise IQ modulator and an integer-fractional PLL/VCO. This component is designed to operate within a wide frequency range of 300 MHz to 4.8 GHz, making it versatile for various wireless communication applications. The device features a VCO with integrated frequency dividers, allowing for a continuous tuning range and the ability to accept input from an external LO or VCO. It also includes internal DC offset adjustment for carrier cancellation and is controlled via a 3-wire serial programming interface (SPI). Additionally, the device supports power-save mode to reduce power consumption while maintaining the VCO lock for fast start-up.
