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.
