MAX19997A Datasheet 1800mhz To 2900mhz Downconversion Mixer

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4288; Rev 0; 10/08 www.DataSheet4U.com Dual, SiGe High-Linearity, 1800MHz to 2900MHz Downconversion Mixer with LO.

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.
