Sunnyvale, CA — A fully integrated, 2000 MHz to 3000 MHz, downconverting mixer with an on-chip LO buffer, the MAX19996 has been designed using a proprietary, monolithic SiGe process from Maxim Integrated Technologies to deliver an industry-leading combination of linearity, noise performance, and component integration. This single IC provides a fully integrated downconversion channel with +24.5 dBm (typical) IIP3, 8.7 dB (typical) conversion gain, and 9.6dB (typical) noise figure.
Further, the MAX19996 claims an industry-best 2RF-2LO spurious rejection of 69 dBc for an RF level of -10 dBm, and 64 dBc for a level of -5 dBm. The mixer specifically targets 3G/4G wireless-infrastructure applications in which high linearity and a low noise figure are critical for enhanced receiver sensitivity and blocker immunity. These include 2.3 GHz to 2.8 GHz WCS, LTE, WiMAX, and MMDS base stations.
As a complete SiGe downconverter, the MAX19996 integrates a state-of-the-art mixer core, two amplifiers, two baluns, and dozens of discrete components. The device's 8.7 dB conversion gain enables the elimination of a complete IF amplifier stage within the receiver lineup. The mixer's outstanding 2RF-2LO performance can also ease the filtering requirements of close-in harmonics, thus leading to simpler and more cost-effective filter designs. Through this combination of integration and performance, the device reduces downconverter solution size by a factor of 2x and the discrete part count by 34 percent.
The MAX19996 is packaged in a compact, 5-mm x 5-mm, 20-pin TQFN and is pin-compatible with a variety of the company's mixers.
