AD8342 CIRCUIT DESCRIPTION The AD8342 is an active mixer, optimized for operation within the input frequency range of near dc to 2.4 GHz. It has a differential, high impedance RF input that can be terminated or matched externally. The RF ...
Page 15
AC INTERFACES The AD8342 is designed to downconvert radio frequencies (RF) to lower intermediate frequencies (IF) using a high- or low-side local oscillator (LO). The LO is injected into the mixer core at a frequency higher or lower than the ...
