DC block with an inner block design (capacitor placed at the center conductor).
It possesses a low cutoff frequency of 20Khz combined with an upper frequency range of 6 GHz. With this wide frequency span (over 5 decades) it is possible to use this DC-Block from the LF band all the way up to the UHF band.
The DC block is designed for 50 Ohm systems and exhibits a very low return loss at both SMA ports.
The DC block is housed in a CNC machined aluminum enclosure.
