TRF37T05IRGER

300 - MHz至4 GHz的正交调制器 300-MHz to 4-GHz Quadrature Modulator

The TRF37T05 is a low-noise direct quadrature modulator with exceptional TDD performance. It is capable of converting complex modulated signals from baseband or IF directly up to RF. The TRF37T05 is a high-performance, superior-linearity device that is ideal to up-convert to RF frequencies of 300 MHz Note: appropriate matching network is required for optimal performance at 300 MHz through 4 GHz. The modulator is implemented as a double-balanced mixer.

The RF output block consists of a differential-to-single-ended converter that is capable of driving a single-ended 50-Ω load. The TRF37T05 requires a 0.25-V common-mode voltage for optimum linearity performance. The TRF37T05 also provides a fast power-down pin that can be used to reduce power dissipation while maintaining optimized adjusted carrier feed-through performance in TDD applications.

The TRF37T05 is available in an RGE-24 VQFN package.
