LTC5576IUF#PBF

LTC5576 is a high linearity active mixer optimized for upconverting applications requiring wide input bandwidth, low distortion and low LO leakage. The integrated output transformer is optimized for 4GHz to 6GHz applications, but is easily retuned for output frequencies as low as 3GHz, or as high as 8GHz, with minor performance degradation. The input is optimized for use with 1:1 transmission-line baluns, allowing very wideband impedance matching. The LO input port is single-ended and requires only 0dBm of LO power to achieve excellent distortion and noise performance while also reducing circuit requirements. It offers low LO leakage, reducing the demands of output filtering to meet LO suppression requirements. It is used in applications such as wideband transmitters, 4G and 5G wireless infrastructure, fixed wireless access equipment, wireless repeaters.
