RF Filter Lowpass OWBP-26504000-28
Model OWBP-26504000-28 is a WR-28 waveguide lowpass filter with a passband frequency from 26.5 to 40 GHz and a rejection frequency 48 to 90 GHz.
Due to the waveguide cut off nature, the low side of the filter has rejection range of DC to 21 GHz. The filter provides a nominal insertion loss of 1.0 dB across its passband and a typical rejection of 60 dB. Since the high end cutoff frequency can be changed by modifying the design, custom designs can be offered under different model numbers.

增益14.5dBi,频率 0.61GHz-0.96GHz, 双波束通讯龙勃透镜天线 OLLA-69-2B
通讯龙勃透镜天线是一种球形介质透镜天线,它通过介质将微波聚焦到焦点。通讯龙勃透镜天线因其高增益、低剖面和多馈源多波束工作而广泛应用于微波、毫米波、移动通信、卫星通信和射电天文学。
该分布具有球面对称性,使得龙勃透镜球面上的任何一点都是透镜球面的焦点。因此,只要控制天线馈源在球面上的位置,电磁辐射波束就可以指向任何方向,并且随着馈源在球面上位置的变化,不存在焦点问题。
由于透镜的介质分布特性,天线对电磁波的频带相对不敏感,因此频带可以很宽。提供频率范围为0.4至110 GHz的定制通讯龙勃透镜天线。在2.17 GHz-3.3 GHz的标准增益值和相应的半功率波束宽度是20 dBi和18度。其他增益值可定制。3D打印天线可以连接到标准波导接口。其他定制的源也是可用的。
