com Dual, SiGe High-Linearity, 1800MHz to 2900MHz Downconversion Mixer with LO Buffer General Description The MAX19997A dual downconversion mixer is a versatile, highly integrated diversity downconverter that provides high linearity and low noise figure for a multitude of 1800MHz to 2900MHz base-station applications.
The MAX19997A fully supports both low- and high-side LO injection architectures for the 2300MHz to 2900MHz WiMAX ™ , LTE, WCS, and MMDS bands, providing 8.
7dB gain, +24dBm input IP3, and 10.
3dB NF in the low-side configuration, and 8.
7dB gain, +24dBm input IP3, and 10.
4dB NF in the high-side configuration.
Highside LO injection architectures can be further extended down to 1800MHz with the addition of one tuning element (a shunt inductor) on each RF port.
The device integrates baluns in the RF and LO ports, an LO buffer, two double-balanced mixers, and a pair of differential IF output amplifiers.
The MAX19997A requires a typical LO drive of 0dBm and a supply current guaranteed below 420mA to achieve the targeted linearity performance.
The MAX19997A is available in a compact 6mm x 6mm, 36-pin thin QFN lead-free package with an exposed pad.
Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +85°C.
