Prezentare generală a produsului

The TRF370417EVM is an evaluation module for TRF370417 direct launch quadrature modulator. The evaluation module also intended for evaluation of TRF370333/317/315 direct launch quadrature modulators. The quadrature modulator is used for upconversion of signals from the transmit chain DAC to the RF power amplifier device. Evaluating modulator complex performance involves careful bias voltage setup, an LO signal, and two differential (I/Q) signals at the input of the modulator. The TRF370417 is a low noise direct quadrature modulator, capable of converting complex modulated signals from baseband or IF directly up to RF. The TRF370417 is a high performance, superior linearity device that operates at RF frequencies of 50MHz through 6GHz. The modulator is implemented as a double balanced mixer. The RF output block consists of a differential to single ended converter and an RF amplifier capable of driving a single ended 50 load without any need of external components.
