Texas Instruments LMX8410L High-Performance Mixers
Texas Instruments LMX8410L High-Performance Mixers offer a wide RF frequency input from 4GHz to 10GHz in a high-performance wideband I/Q demodulator. The LMX8410L provides an excellent dynamic range for high-performance applications with an IIP3 of 28dBm and a noise figure of 15dB (both at 5GHz). The device offers a large complex bandwidth of 2.7GHz for high data-rate applications. The LMX8410L Mixers provide an automatic DC offset correction algorithm that reduces the offset to less than ±2mV.
Using the SPI interface, fine control of gain and phase with I and Q channels is enabled to achieve a high image rejection. The LMX8410L has a high level of integration saving board space and complexity. The device integrates a wideband RF input balun, eliminating the need for external baluns. Also integrated is a high-performance PLL and VCO, eliminating the need for external LO and LO driver. Furthermore, the LMX8410L integrates an IF amplifier and several low noise LDOs, reducing complexity and simplifying the board.
