This mixer features a frequency range of 1800 MHz to 2100 MHz. It operates from a single 5 V supply and provides 16 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 ATR0786 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. Figure 1.
