Texas Instruments TRF372017 300 MHz to 4.8GHz Quadrature Modulator with integrated wideband PLL/VCO TRF372017IRGZT

The TRF372017IRGZT is a high-performance quadrature modulator designed for applications requiring direct up-conversion from baseband to RF frequencies. It operates over a wide frequency range from 300 MHz to 4.8 GHz and integrates a low-noise PLL/VCO, which allows for a continuous tuning range. The device features a low phase noise of -132 dBc/Hz at 1 MHz offset and a low noise floor of -160 dBm/Hz, making it suitable for demanding wireless communication applications. The modulator provides a single-carrier WCDMA ACPR of 76 dBc at -8 dBm output power, with an OIP3 of 26 dBm and a P1dB of 11.5 dBm. It supports both internal and external local oscillator inputs and allows for internal DC offset adjustment for carrier cancellation. The device is controlled via a 3-wire SPI interface and includes a power-save mode to reduce power consumption while maintaining VCO lock for quick start-up. The TRF372017IRGZT is packaged in a compact 48-pin VQFN, suitable for integration into space-constrained designs. It operates within a temperature range of -40 to 85 degrees Celsius, making it suitable for various environmental conditions. This modulator is ideal for applications in wireless infrastructure, including CDMA, TDMA, LTE, and point-to-point wireless access systems.
