The LTC?5510 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 transmissionline 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.
APPLICATIONS

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.
