LTC5552 Image

The LTC5552 from Analog Devices is a double balanced mixer with wideband matching from 3 GHz to 20 GHz. The mixer can be used for both up and down conversion applications. When used in up conversion applications its DC capable differential IF port enables the LO to be close in frequency to the RF. Its low LO to RF leakage of less than -25 dBm greatly eases the burden on the external filter. Additionally, the mixer delivers excellent linearity of 20.1 dBm IIP3 at 14 GHz, and 18.3 dBm at 17 GHz. The device integrates a broadband LO buffer, requiring only 0 dBm drive and effectively eliminating an external high power LO amplifier circuit. Moreover, the LTC5552 integrates a wideband balun transformer in its RF port, allowing single-ended 50 ohms matched operation over its specified frequency range. All these features result in minimum external components, simplified design and a very small solution size. The LTC5552's exceptionally wide bandwidth and performance is ideal for a broad range of applications, including 5G broadband wireless access, microwave backhaul, satellite broadband radios, radar systems, active antenna arrays, X, Ku and Ka band transceivers, RF test equipment, spectrum analysis and satellite communications.
