T0790
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 inte-
grated 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.
