Description
The Agilent R/Q/U/V 281 adapters have:
•Excellent repeatability
•Measurement v ersatility
•WR-28, WR-22, WR-19, WR-15 (R, Q, U, V band) waveguide
•Precision 1.85 mm and 2.4 mm coax connectors
Increased Measurement
Versatility
Excellent AccuracyLow SWR transitions reduce mismatch uncertainty and excellent
Coax measurements to 65 GHz. The Agilent 281 family of precision
millimeter waveguide-to-coax adapters offers a simple, low SWR transition
between transmission media. Take advantage of stable, low loss and low
SWR waveguide when measuring coaxial devices at higher frequencies. Or
keep the convenience of coax, even when testing waveguide components.
Agilent R/Q/U/V 281 adapters increase the versatility of existing test sets to
measure both coax and waveguide components.
repeatability ens ures consistent measurements. Available with both male and
female connectors, these adapters help microwave engineers combine the
best test components from each transmission media. With the Agilent
R/Q/C1/V 281 adapters, engineers can balance the merits of coax and
waveguide to achie ve the bes t combinat ion of ac curacy, cost and ease-of-use.
