Analog Devices®5548 Microwave Mixer

Analog Devices' LTC5548 is a 2 GHz to 14 GHz microwave mixer with wideband DC to 6 GHz IF

Image of Analog Devices' LTC5548® Microwave MixerThe LTC5548 from Analog Devices is a high performance, microwave double balanced passive mixer that can be used for frequency up-conversion or down-conversion. The device is similar to the LTC5549, but with a broadband, differential DC to 6 GHz IF port. The LTC5548 is recommended for applications where the IF frequency range extends below 500 MHz. For applications where the IF frequency is always above 500 MHz, the LTC5549 is recommended, since it includes an integrated IF balun.

The LTC5548’s mixer and integrated RF balun are optimized to cover the 2 GHz to 14 GHz RF frequency range. The device includes an integrated LO amplifier optimized for the 1 GHz to 12 GHz frequency range, requiring only 0 dBm 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.

Difficult Design Challenges Solved with 2 to 14 GHz Matched Microwave Mixer Linear Technology’s LTC5548 wideband mixer’s features help designers overcome common challenges for microwave applications.
The Basics of Mixers Mixers are used in a variety of RF/microwave applications, including military radar, cellular base stations, and more. An RF mixer is a three-port passive or active device that can modulate or demodulate a signal.
Passive Mixers in Downconverter Applications While most downconverting mixer designs typically use an active or current-commutating topology, new passive mixer ICs can deliver markedly better performance with comparable linearity.
