MAX19995：Dual, SiGe, High-Linearity, 1700MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch

Lowest Noise, Highest Linearity 1700MHz to 2200MHz Dual, SiGe Mixer for DCS/PCS, CDMA, WCDMA, and LTE Base Stations, Featuring Superior IIP3, NF, and 2RF-2LO Performance

The MAX19995 dual-channel downconverter provides 9dB of conversion gain, +24.8dBm input IP3, +13.3dBm 1dB input compression point, and a noise figure as low as 9dB for 1700MHz to 2200MHz diversity receiver applications. With an optimized LO frequency range of 1400MHz to 2000MHz, this mixer is ideal for low-side LO injection architectures. High-side LO injection is supported by the MAX19995A, which is pin-pin and functionally compatible with the MAX19995. In addition to offering excellent linearity and noise performance, the MAX19995 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 MAX19995 requires a nominal LO drive of 0dBm and a typical supply current of 297mA at VCC = 5.0V or 212mA at VCC = 3.3V. The MAX19995/MAX19995A are pin compatible with the MAX19985/MAX19985A series of 700MHz to 1000MHz mixers and pin similar with 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 MAX19995 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, from TC = -40°C to +85°C.
