The MAX19993 dual-channel downconverter is designed to provide 6.4dB of conversion gain, +27dBm input IP3, 15.4dBm 1dB input compression point, and a noise figure of 9.8dB for 1200MHz to 1700MHz diversity receiver applications. With an optimized LO frequency range of 1000MHz to 1560MHz, this mixer is ideal for low-side LO injection architectures. High-side LO injection is supported by the MAX19993A, which is pin-pin and functionally compatible with the MAX19993.
In addition to offering excellent linearity and noise performance, the MAX19993 also yields a high level of component integration. This device includes two double-balanced passive mixer cores, two LO buffers, a dual-input LO selectable switch, and a pair of differential IF output amplifiers. Integrated on-chip baluns allow for single-ended RF and LO inputs. The device requires a nominal LO drive of 0dBm and a typical supply current of 337mA at VCC = +5.0V or 275mA at VCC = +3.3V.
The MAX19993 is pin compatible with the MAX9985/MAX19985A/MAX9995/MAX19993A/MAX19994/MAX19994A/
MAX19995/MAX19995A series of 700MHz to 2200MHz mixers and pin similar to the MAX19997A/MAX19999 series of 1850MHz to 4000MHz mixers, making this entire family of downconverters ideal for applications where a common PCB layout is used across multiple frequency bands.
The device is available in a 6mm × 6mm, 36-pin TQFN package with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +85°C.
