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. Figure 1.
