HUBER+SUHNER series 3410 high-power gas discharge tube (GDT) protectors with integrated high-pass filter and DC injection port belong to the family of ultimate GDT protectors – suitable to meet the demanding high RF performance and protection requirements of future mobile communications transceivers with DC powering of outdoor equipment. The customer is freed from any RF power and IM performance considerations. Thus, the protectors are especially suitable for multicarrier systems. The integrated high-pass provides an improved protection performance to series 3409 protectors. As the high-pass filter means a DC-blocking on the protected side of the component, this design is especially suitable for products with integrated DC injection facility.
