Abstract：The performance of local oscillator anti-phase balance mixer is analyzed by using the system anal-ysis method.Then,a double balance mixer is designed by adopting the LT5522 chip.Finally,the practical-ity circuits of a receiver are tested and analyzed.A mirror frequency suppression filter is configured at the input end of the mixer,and a low noise amplifier is configured at the input port.By doing so,the whole down-mixer circuits observe a better noise factor,and this noise factor is less than 1 .2 dB of the whole cir-cuits to satisfy the needs.
