The LTC5576 is a high linearity active mixer optimized for upconverting applications requiring wide input bandwidth, low distortion and low LO leakage. The integrated output transformer is optimized for 4GHz to 6GHz applications, but is easily retuned for output frequencies as low as 3GHz, or as high as 8GHz, with minor performance degradation. The input is optimized for use with 1:1 transmission-line baluns, allowing very wideband impedance matching.

The LO input port is single-ended and requires only 0dBm of LO power to achieve excellent distortion and noise performance while also reducing circuit requirements. The LTC5576 offers low LO leakage, reducing the demands of output filtering to meet LO suppression requirements.

The LTC5576 is optimized for 5V but can also be used with a 3.3V supply with slightly reduced performance. The enable function allows the part to be easily shut down for further power savings.

Product Details

Demonstration circuit 2322A is designed for evaluation of the LTC5576 active upconverting mixer with very wide input bandwidth and low distortion. Its OUT port is optimized for 4GHz to 6GHz applications, but is easily retuned for output frequencies as low as 3GHz, or as high as 8GHz with minor performance degradation. The IN port is optimized for 30MHz to 6GHz operation while the LO port is always 50Ω matched from 1GHz to 8GHz.
