2 GHz Band Power Dividers/Combiners
C/D Series
a73Features
1.Division System
The micro stripline method, which uses the
principle of the /4 impedance converter, provides
excellent high frequency performance.
2.High Performance
The low insertion loss and high isolation (of over 20
dB) afforded by the Wilkinson circuit structure make
these power dividers ideal for use in portable
telephone base stations, measuring instruments,
and for measurements.
3.Highly Reliable Design
Connectors are of the SMA type and use stainless
steel for extremely high performance.
The case uses corrosion-resistant aluminum and is
both miniature and lightweight.
a73Product Specifications
a71Please see the specification items for details concerning insertion loss, VSWR, and isolation.
a71The test method conforms to MIL-STD-202.
