LTC5510IUF#PBF

LTC5510 is a high linearity mixer optimized for applications requiring very wide input bandwidth, low distortion, and low LO leakage. The chip includes a double-balanced active mixer with an input buffer and a high speed LO amplifier. The input is optimized for use with 1:1 transmission line baluns, allowing very wideband impedance matching. The mixer can be used for both up- and down-conversion and can be used in wideband systems. The LO can be driven differentially or single-ended and requires only 0dBm of LO power to achieve excellent distortion and noise performance, while also reducing external drive circuit requirements. It offers low LO leakage, greatly reducing the need for output filtering to meet LO suppression requirements. It is used in application like wideband receivers/transmitters, cable downlink infrastructure, HF/VHF/UHF mixer, wireless infrastructure etc.
