TRF3705 Overview
The TRF3705 is a low-noise direct quadrature modulator, capable of converting plex 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 (Note: appropriate matching network is required for optimal performance at 300 MHz) through 4 GHz.
