The LTC5548 is a high performance, microwave double balanced passive mixer that can be used for frequency upconversion or downconversion. The device is similar to the LTC5549, but with a broadband, differential DC to 6GHz IF port. The LTC5548 is recommended for applications where the IF frequency range extends below 500MHz. For applications where the IF frequency is always above 500MHz, the LTC5549 is recommended, since it includes an integrated IF balun.

The LTC5548’s mixer and integrated RF balun are optimized to cover the 2GHz to 14GHz RF frequency range. The device includes an integrated LO amplifier optimized for the 1GHz to 12GHz frequency range, requiring only 0dBm drive. The device also includes an integrated LO frequency doubler, which can be enabled or disabled with a CMOS-compatible control pin.

The LTC5548 delivers exceptionally high IIP3 and P1dB, in addition to very low LO to RF and LO to IF leakages. The part also offers high integration in a small package.

Product Detail

Demonstration circuit 2461A is optimized for evaluation of the LTC5548 passive double-balanced mixer with integrated LO frequency doubler. Its RF port is matched to 50Ω from 2GHz to 13.6GHz with 9dB return loss, and the LO port is matched to 50Ω from 1GHz to 12GHz with 10dB return loss. The differential IF port is usable from DC to 6GHz. The LTC5548 can be used for upconverting and downconverting applications.
