High Linearity
SiGe Active
Receive Mixer
Description
The T0780 is a high linearity active mixer which is manufactured using Atmel’s
advanced Silicon-Germanium (SiGe) technology. This mixer features a frequency
range of 800 MHz to 1000 MHz. It operates from a single 5-V supply and provides
10 dB of conversion gain while requiring only 0 dBm input to the integrated LO driver.
An IF amplifier is also included.
The T0780 incorporates internal matching on each RF, IF and LO port to enhance
ease of use and to reduce the external components required. The RF and LO inputs
can be driven differentially or single-ended.
