MILPITAS, CA – February 1, 2017 – Linear Technology introduces the LTC5566, a new wideband, high dynamic range dual channel mixer with integrated programmable variable gain IF amplifiers. This dual mixer has a very wide, 300MHz to 6GHz input frequency range, specifically optimized and with extensive characterization at the emerging 3.6GHz and 4.5GHz 5G bands, as well as the established 4G bands. Moreover, the device supports bandwidths up to 400MHz to meet the needs of the growing sub-6GHz 5G wireless access equipment. This dual mixer has outstanding dynamic range, with Input P1dB of +11.5dBm and Input IP3 of +25.5dBm at 3.6GHz. At higher frequencies, up to 5.8GHz, its IIP3 sustains more than +24dBm. The device’s integrated IF amplifier boosts the overall power conversion gain to a maximum of 12dB. The gain of each channel is independently programmed in precise 0.5dB steps via the on-chip SPI bus. So, with each channel driving an A/D converter, the fine gain control provides a simple means to balance the gain of the two channels and calibrate to the optimum level with minimal external components.
