Product Summary

The LT5579IUH#PBF is a High Linearity Upconverting Mixer. The LT5579IUH#PBF mixer is a high performance upconverting mixer optimized for frequencies in the 1.5GHz to 3.8GHz range. The single-ended LO input and RF output ports simplify board layout and reduce system cost. The mixer needs only –1dBm of LO power and the balanced design results in low LO signal leakage to the RF output. At 2.6GHz operation, the LT5579IUH#PBF provides high conversion gain of 1.3dB, high OIP3 of +26dBm and a low noise floor of –157.5dBm/Hz at a –5dBm RF output signal level. The LT5579IUH#PBF offers a high performance alternative to passive mixers. Unlike passive mixers, which have conversion loss and require high LO drive levels, the LT5579IUH#PBF delivers conversion gain at significantly lower LO input levels and is less sensitive to LO power level variations. The lower LO drive level requirements, combined with the excellent LO leakage performance, translate into lower LO signal contamination of the output signal. The applications of the LT5579IUH#PBF include 2.6GHz and 3.5GHz WiMAX Basestations, 2.4GHz ISM Band Transmitters and High Performance Transmitters.
