DESCRIPTION
The TRF3702 is an ultralow-noise direct quadrature modulator that is capable of converting complex input
signals from baseband or IF directly up to RF. An internal analog combiner sums the real and imaginary
components of the RF outputs. This combined output can feed the RF preamp at frequencies of up to 2.5 GHz.
The modulator is implemented as a double-balanced mixer. An internal local oscillator (LO) phase splitter
accommodates a single-ended LO input, eliminating the need for a costly external balun.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
