Texas Instruments TRF3705 300MHz to 4GHz Quadrature Modulator

Texas Instruments TRF3705 300MHz to 4GHz low-noise direct quadrature modulator is capable of converting complex modulated signals from baseband or IF directly up to RF. TI TRF3705 quadrature modulator is a high-performance, superior-linearity device that is ideal to up-convert to RF frequencies of 300MHz. 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 TI TRF3705 requires a 0.25V common-mode voltage for optimum linearity performance. TI TRF3705 quadrature modulator also provides a fast power-down pin that can be used to reduce power dissipation in TDD applications. The TRF3705EVM evaluation module is designed for the evaluation of the TRF3705 direct-launch quadrature modulator for applications in the transmit path of base stations and communication equipment.
