AK1224
900MHz Low Noise Mixer
1. Overview
The AK1224 is a high linearity and low noise mixer. RF frequency range coverage is from 100 to 900MHz and IF
coverage is from 20 to 100MHz. AK1224 can be driven by a single ended RF input and a low-power differential LO
input that can be driven with a differential or single ended LO signal. IF output ports are differential open drain
outputs. The analog circuit characteristics and power consumption performances can be optimized by the
resistance connected to the BIAS Pin.
