RF Power Combiners, Couplers, & Dividers
Manufacturers & Services
These companies can supply your requirements for RF combiners, couplers, & dividers.
All ranges of form factors, power handling, coupling and isolation values, connector types, and other parameters are
available. Most will design and manufacture custom products to meet your needs. I of course request that you check
with RF Cafe Advertisers first, out of an appreciation for their underwriting of the website.
RF power combiners
and dividers are compliments of each other and can usually be used interchangeably. The power combiner takes multiple
inputs and effectively algebraically adds them together at the output. The power divider splits the input into two
or more branches, usually with an equal portion to each branch. Sometimes there are phase shifts deliberately inserted
in one or more of the branches.
RF power couplers are also reciprocal devices in that the coupled ports can be used to sample a portion of the
mainline power, or they can be used to inject a signal into the main signal path. A bidirectional coupler provides
a sample port in both the forward and reverse directions; they are often used to measure VSWR.
One important thing to keep in mind is that specified values for coupling are only guaranteed at 50+j0 ohms, or
whatever the characteristic impedance of the attenuator model happens to be (50 and 75 ohms most common). The farther
away from the characteristic impedance the connected ports are, the farther from the spec the coupling value will
