Small 2mm Г— 2mm 10-Lead QFN Package The LTCВ®5562 is a versatile low power mixer optimized for
applications requiring wide input bandwidth, low distortion and low LO leakage. This mixer can be used for either
upconverting or downconverting applications, and provides
a nominal conversion gain of 1dB. The differential input is
optimized for use with a 1:1 transmission-line balun, the
input is 50Ω broadband matched from 30MHz to 7GHz.
The LO can be differential or single-ended and requires
only –1dBm of LO power to achieve excellent distortion
and noise performance. The impedance match at the LO …
