16-Lead (4mm Г— 4mm) QFN Package The LTCВ®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 …
