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 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
