GRF7001 is a broadband, high-linearity mixer with integrated LO buffer that can be used as either an up or down converter.
The device inputs and outputs are single-ended and are easily matched to 50 ohms. Implementation requires an external image-reject filter on the RF port and an IF bandpass filter on the IF port. Pins 4 and 6 can be used for either RF or IF with appropriate filtering in place.
The integrated LO buffer is operated from a single positive supply of 3.0 to 5.0 V for both the VDD and VENABLE inputs.
