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.
