The LTC5510 is a high linearity mixer optimized for applications requiring very wide input bandwidth, low distortion, and low LO leakage. The chip includes a double-balanced active mixer with an input buffer and a high speed LO amplifier. The input is optimized for use with 1:1 transmission line baluns, allowing very wideband impedance matching. The mixer can be used for both up- and down-conversion and can be used in wideband systems.
The LO can be driven differentially or single-ended and requires only 0dBm of LO power to achieve excellent distortion and noise performance, while also reducing external drive circuit requirements. The LTC5510 offers low LO leakage, greatly reducing the need for output filtering to meet LO suppression requirements.
The LTC5510 is optimized for 5V but can also be used with a 3.3V supply with slightly reduced performance. The shutdown function allows the part to be disabled for further power savings.

DC1983A: Demo Board for the LTC5510 1MHz to 6GHz Wideband High Linearity Active Mixer.
Demonstration circuit 1984A showcases the LTC5510. wideband high linearity active mixer for VHF/UHF upmixer applications, where a 70MHz input signal is upconverted to the 100MHz to 1GHz output range. Its input port is optimized for 30MHz to 2.6GHz, and its output port is optimized for 10MHz to 1.3GHz. The LO input can be either high side or low side.
Tools & Simulations
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
