With a 1700MHz to 3000MHz RF frequency range and a 1900MHz to 3000MHz LO frequency range, this mixer is ideal for high-side LO injection architectures. In addition to offering excellent linearity and noise performance, the MAX2043 also yields a high level of component integration. The MAX2043 integrates baluns in the RF and LO ports, a d...
