Description
The ATR0787 is a high linearity active mixer which is manufactured using Atmel´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 2100 MHz to 2500 MHz. It operates from a
single 5 V supply and provides 17 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 ATR0787 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.
