Observe precautions for handling. 1700 - 2300 MHz High Linearity SiGe Active Receiver Mixer T0781 Description The T0781 is a high linearity active mixer which is manufactured using Atmel’s 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. Preliminary Figure 1. Block Diagram RFP RFN 4 5 1 16 13 IFP IFN LOP 12 LON Rev. 4534B–SIGE–01/03 1 Pin Configuration Figure 2.
