This double-balanced mixer can be driven by a single-ended LO source and requires only - 2d Bm of LO power. The balanced design results in low LO leakage to the output, while the integrated input amplifier provides excellent LO to IN isolation. The signal ports can be impedance matched to a broad range of frequencies, which allows the LT5560 to be used as an up- or down-conversion mixer in a wide variety of applications. The LT5560 is characterized with a supply current of 10m A; however, the DC current is adjustable, which allows the performance to be optimized for each application with a single resistor. For example, when biased at its maximum supply current (13.4m A), the typical upconverting mixer IIP3 is +10.8d Bm for a 900MHz output. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
