摘要
本文主要采用单平衡镜像抑制混频结构,射频信号通过前级低噪声放大器VMMK-1225降噪处理,通过90°耦合网络将射频信号功分两路,分别送入两路单平衡混频电路,然后将两路单平衡混频电路中输出的中频信号通过低通滤波电路来改善带外抑制度,最后,两路信号经过90°合路器获取中频信号。实现射频频率3.1GHz-3.6GHz,中频频率250MHz-300MHz,噪声系数小于3.5d B,变频增益为4.6d B-5.8d B,增益波动小于1.2d B,镜像抑制优于20.5d B,1d B压缩点大于-18d Bm,杂散抑制优于35d B。
This paper adopts single-balanced image-rejection structure, the first stage low noise amplifier(LNA), VMMK-1225 is used to reduce the noise figure, and the next stage is 90°coupling networks to divide the RF signal into two ways, which are both the single-balanced circuits, then, the outputs are filtered by the low-pass filters to improve the rejection out of the band, finally, the two-way signals are combined by the 90°IF combiner to obtain the IF signal. The experiment achieves the RF band 3.1GHz-3.6GHz, and the IF band 250MHz-300 MHz, noise figure is less than 3d B, conversion gain is between 4.5d B and 6d B, gain ripple is less than 1.5d B, image rejection is better than 21 d B, 1d B compression is large than-18 d Bm, spurious band rejection is better than 35 d B.
