ATR0785
Preliminary
Description
The ATR0785 is a highly linearity active mixer which is manufactured using Atmel麓s
advanced Silicon Germanium technology for the use in a variety of high performance
requiring RF systems such as digital communications.
This mixer features a frequency range of 800 MHz to 1000 MHz. It operates from a
single 5 V supply and provides 14 dB of conversion gain while requiring only 0 dBm
input to the integrated LO driver. An IF and an LO amplifier is also included.
The ATR0785 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.
