The LTC5510 is a high performance mixer with very wide frequency range, extending to 6GHz. It provides a continuous 50ohm matched input from 30MHz to 6GHz, while delivering outstanding linearity and gain flatness. These features enable applications to work over a wider frequency span without needing to rematch the input for different frequency bands, thereby reducing cost and simplifying design. Additionally, the LTC5510's output can reach up to 4.5GHz, allowing the device to be used either as an upconversion or downconversion mixer, making it highly versatile. The mixer has excellent linearity performance of 27.8dBm OIP3 as an upconverting mixer, and 24.9dBm IIP3 as a downconverting mixer at 2GHz. Moreover, its conversion gain of 1.1dB and noise figure of 11.6dB produce outstanding dynamic range performance for robust radios. The LTC5510's extended frequency capability simplifies a wide variety of applications such as cellular basestations, wireless repeaters, microwave backhauls that can cross over multiple frequency bands. Moreover, the device's unique capability and performance are ideally suited for other applications including VHF/UHF band radios, broadcast and white-space radios, military communications, cable systems, RF and wireless test equipment, public safety radios, radar receivers, satellite communications and wireless professional microphone receivers.The LTC5510's minimum external components and it's 16-lead, 4mm x 4mm QFN package result in a highly compact solution footprint. It is optimized for single 5V supply operation but can also be powered with a 3.3V supply, supply current is 105mA. This device is specified for operation from -40°C to 105°C to support extended operating temperature environments and is priced starting at $4.90 each in 1,000-piece quantities.
