Observe precautions for handling. Description The T0790 is a direct quadrature modulator using Atmel’s Silicon-Germanium (SiGe) process. This modulator features a frequency range of 700 to 2700 MHz with excellent carrier and sideband suppression and a very low noise floor. It operates from a single 5 V supply and provides -11 dBm of power while requiring only 0 dBm input to the integrated LO driver. An RF and an LO amplifier are also included. The T0790 incorporates internal matching on each RF, IF and LO port to enhance ease of use and to reduce the external components required. The LO input can be driven differentially or single ended.

This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
