3 Description
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 50 MHz
through 6 GHz. 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-Ω load
without any need of external components. The
TRF370417 requires a 1.7-V common-mode voltage for optimum linearity performance.
