The LTC5553 is a high performance, microwave double balanced passive mixer that can be used for frequency upconversion or downconversion.

The LTC5553’s mixer and integrated RF balun are optimized to cover the 3GHz to 20GHz RF frequency range. The device includes an integrated LO amplifier optimized for the 1GHz to 20GHz frequency range, requiring only 0dBm drive. The integrated IF balun is optimized to cover a very wide, 500MHz to 9GHz, frequency range while providing a single-ended 50Ω interface.

The LTC5553 delivers exceptionally high IIP3 and P1dB, in addition to low LO to RF and LO to IF leakages. The part also offers a high level of integration in a small package.
