TRF370315 0.4 - 4.0 GHz IQ Modulator

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 350 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-Ω 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.
