Finally, VSWR can be adjusted by inserting a
fixed attenuator in front of a mismatched path.
It consists of a 50 dB ([+ or -]2 dB) high power
fixed attenuator integrated into the same package with a variable attenuator with continuous resolution from 0 to 15 dB.
These
fixed attenuator pads feature an innovative GroundWrap design that eliminates the need for separate ground bonding.
A cascade of two such phase shifters buffered by a 3 dB
fixed attenuator produces a 40 [degrees] tuning range.
Common applications for these
fixed attenuators include power limiting, impedance matching and signal leveling inside RF test systems.
These
fixed attenuators operate from DC up to 6 GHz and are offered in economical brass or stainless steel construction for durability.
Pasternack's new 40 GHz
fixed attenuators are designed with 2.92mm connectors and allow input power of 2 Watts.
