Overview
The TRF370417IRGER is a high-performance, low-noise direct quadrature modulator produced by Texas Instruments. This device is designed to convert complex modulated signals from baseband or IF directly to RF frequencies ranging from 50 MHz to 6 GHz. It is implemented as a double-balanced mixer and includes a differential to single-ended converter and an RF amplifier, capable of driving a single-ended 50-Ω load without the need for external components. The modulator operates with a single supply voltage of 4.5 V to 5.5 V and requires a 1.7-V common-mode voltage for optimum linearity performance.
