The TRF3705 is a low-noise direct quadrature
modulator, capable of converting complex modulated
signals from baseband or IF directly up to RF. The
TRF3705 is a high-performance, superior-linearity
device that is ideal to up-convert to RF frequencies of
300 MHz (1) 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 TRF3705
requires a 0.25-V common-mode voltage for optimum
linearity performance. The TRF3705 also provides a
fast power-down pin that can be used to reduce
APPLICATIONS
power dissipation in TDD applications.
