The device is similar to the LTC5549, but with a broadband, differential DC to 6GHz IF port. The LTC5548 is remended for applications where the IF frequency range extends below 500MHz. For applications where the IF frequency is always above 500MHz, the LTC5549 is remended, 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 0d Bm drive. The device also includes an integrated LO frequency doubler, which can be enabled or disabled with a CMOS-patible control pin. The LTC5548 delivers exceptionally high IIP3 and P1d B, in addition to very low LO to RF and LO to IF leakages. The part also offers high integration in a small package.
