3 Description
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.
