Linear Technology: Dual-broadband RF mixer enables 4G MIMO multimode receivers by drawing 300 mW/ch

In order to make LTE, a 4G (fourth-generation) high-data-rate wireless technology attractive to the carrier for deployment, basestation manufacturers worldwide are trying to build a multiband, multimode platform that is easily field configured for use in any frequency band and standard to make the deployment cost attractive. The 26.8-dBm IIP3 LTC5569 dual-broadband RF mixer accomplishes this by combining 26.8 dBm IIP3, 300mW/ch, and a wide 300-MHz to 4-GHz frequency range (see www2.electronicproducts.com/26_8_dBm_IIP3_dual_broadband_RF_mixer_draws_300_m W_charticlehlcn07_jul2011-html.aspx).

So a receiver such as that based on the LTC5569, is capable of working in all of the 700-MHz, 880-MHz, 1.7-GHz, 1.8-GHz, 1.9-GHz, 2.4-GHz, and 2.6-GHz bands. In addition, within each band, the receiver must receive signals that are 60 MHz wide, compared to the previous 20 MHz wide without sacrificing performance. The LTC5569 meets both of these requirements with outstanding performance.
