Wideband 2GHz to 14GHz Mixer with Integrated LO Frequency Doubler Delivers IF Bandwidth from DC to 6GHz

MILPITAS, CA - March 7, 2016 - Linear Technology announces the LTC5548, a double balanced mixer that operates either as an up- or downconverter with an exceptionally wide frequency range from 2GHz to 14GHz. The LTC5548 features integrated balun transformers at the RF and LO ports, providing 50Ω match from 2GHz to 13.6GHz and from 1GHz to 12GHz at each port, respectively, while enabling single-ended operation. Additionally, the IF port is capable of DC to 6GHz, supporting wideband transmitters and receivers at the baseband. The LTC5548 has high linearity of 24.4dBm IIP3 at 5.8GHz, and 21.4dBm at 9GHz.
The LTC5548 simplifies microwave transmitter and receiver designs with its integrated LO buffer, requiring only a 0dBm drive, effectively eliminating an external high power LO amplifier circuit
