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.

Product Details

Demonstration circuit DC2566A is optimized for evaluation of the LTC5553 passive double-balanced mixer. Its RF port is broadband matched from 3GHz to 20GHz, and the internal LO amplifier, requiring only a 0dBm drive level, is broadband matched to 50Ω from 1GHz to 20GHz with 10dB Return Loss. The single-ended IF output is broadband matched from 500MHz to 9GHz. The LTC5553 can be used for upconverting and downconverting applications.
