1. Overview
The AK1221 is high linearity mixer. RF and Lo frequency range coverage is from 700 to 3500MHz and IF coverage is from 20 to 200MHz. The RF input provides single-ended 50Ω interface. Lo ports are 50Ω matched and complementary input should be decoupled to the ground. IF output ports are differential open drain outputs. The linearity and power consumption performances can be optimized by the resistance connected to the BIAS Pin.
