Texas Instruments TRF370317 0.4 GHz to 4.0 GHz Quadrature Modulator, 1.7V common-mode voltage TRF370317IRGET

The TRF370317IRGET is a low-noise quadrature modulator designed for RF applications ranging from 0.4 GHz to 4.0 GHz. It features a common-mode voltage of 1.7V, which is essential for optimal linearity performance. The device is capable of converting complex modulated signals directly from baseband or intermediate frequency (IF) to RF, making it suitable for various communication standards including WCDMA, GSM, and LTE. This modulator exhibits a low noise floor of ,Äì163 dBm/Hz and a third-order intercept point (OIP3) of 26.5 dBm, indicating strong linearity performance. It also has a P1dB of 12 dBm and provides unadjusted carrier feedthrough and side-band suppression levels of ,Äì40 dBm and ,Äì45 dBc, respectively. The TRF370317 operates with a single supply voltage ranging from 4.5V to 5.5V and is implemented using silicon-germanium technology, which contributes to its performance characteristics. The device is packaged in a 24-pin VQFN format and is rated for operation over a temperature range of -40¬8C to 85¬8C. This modulator is particularly well-suited for applications in cellular base station transceivers and other wireless communication systems.
