AK1222
900MHz Low Power Mixer
1. Overview
The AK1222 is a low power mixer. RF and LO frequency range coverage from 100 to 900MHz and IF coverage is
from 20 to 100MHz. The RF input provides single-ended 50 interface. LO ports are 50 matched and
complementary inputs should be decoupled to the ground. IF output ports are differential open drain outputs.
The linearity and power consumption performances can optimize with the resistance connected to the BIAS pin.
