Product Details

The MAX19995A dual-channel downconverter is designed to provide 8.7dB of conversion gain, +24.8dBm input IP3, +13.5dBm 1dB input compression point, and a noise figure of 9.2dB for 1700MHz to 2200MHz diversity receiver applications. With an optimized LO frequency range of 1750MHz to 2700MHz, this mixer is ideal for high-side LO injection architectures. Low-side LO injection is supported by the MAX19995, which is pin-pin and functionally compatible with the MAX19995A.

In addition to offering excellent linearity and noise performance, the MAX19995A 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 MAX19995A requires a nominal LO drive of 0dBm and a typical supply current of 350mA at VCC = 5.0V, or 242mA at VCC = 3.3V.

The MAX19995/MAX19995A are pin compatible with the MAX19985/MAX19985A series of 700MHz to 1000MHz mixers and pin similar to the MAX19997A/MAX19999 series of 1800MHz to 4000MHz mixers, making this entire family of downconverters ideal for applications where a common PCB layout is used across multiple frequency bands.

The MAX19995A is available in a 6mm x 6mm, 36-pin thin QFN package with an exposed pad. Electrical performance is guaranteed over the extended temperature range (TC = -40°C to +85°C).
