资 源 简 介

The TRF370315 and TRF370333 are low-noise direct quadrature modulators, capable of converTIng complex modulated signals from baseband or IF directly up to RF. The TRF370315 and TRF370333 are ideal for high-performance direct RF modulaTIon from 400 MHz up to 4 GHz. These modulators are 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. The TRF370333 and TRF370315 devices have different common-mode voltage raTIngs at the I/Q baseband inputs. The TRF370315 requires a 1.5-V common-mode voltage, and the TRF370333 requires a 3.3-V common-mode voltage.
