    • To provide an oscillation module which is able to improve an input level by passing signals in a main signal band while removing near noise and far noise.An oscillation module is provided with an OCXO, an amplifier, and a noise elimination filter. The noise elimination filter includes: a BPF passing a signal in the main signal band and eliminating far noise with respect to the main signal band; an L-BEF eliminating near noise in a low frequency band with respect to the main signal band; and an H-BEF eliminating near noise in a high frequency band with respect to the main signal band. Each filter is configured with a crystal filter.
    • 提供振荡模块,其能够通过在主信号频带中传递信号来改善输入电平,同时消除接近的噪声和远的噪声。 振荡模块配有OCXO,放大器和噪声消除滤波器。 噪声消除滤波器包括:BPF通过主信号频带中的信号并消除相对于主信号频带的远的噪声; 相对于主信号频带,在低频带中消除近邻噪声的L-BEF; 以及相对于主信号频带在高频带中消除接近噪声的H-BEF。 每个滤波器都配置了晶体滤波器。
