T0781
Description
The T0781 is a high linearity active mixer which is manufactured using Atmel鈥檚
advanced Silicon-Germanium technology. This mixer features a frequency range of
1700 MHz to 2300 MHz. It operates from a single 5-V supply and provides 12 dB of
conversion gain while requiring only 0 dBm input to the integrated LO driver. An IF
amplifier is also included.
The T0781 incorporates internal matching on each RF, IF and LO ports to enhance
ease of use and to reduce the external components required. The RF and LO inputs
can be driven differentially or single-ended.
