描述 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.
