5mm Г— 5mm QFN24 Package The LTВ®5579 mixer is a high performance upconverting
mixer optimized for frequencies in the 1.5GHz to 3.8GHz
range. The single-ended LO input and RF output ports
simplify board layout and reduce system cost. The mixer
needs only –1dBm of LO power and the balanced design
results in low LO signal leakage to the RF output. At  2.6GHz
operation, the LT5579 provides high conversion gain of
1.3dB, high OIP3 of +26dBm and a low noise floor of
–157.5dBm/Hz at a –5dBm RF output signal level.
The LT5579 offers a high performance alternative to passive mixers. Unlike passive mixers, which have conversion
loss and require high LO drive levels, the LT5579 delivers …
