Description
SMA JACK
(5 PLS)
M/A-COM’s PD60-0014-04S is designed to provide a low
loss method of combining signals from four amplifiers or
transmitters in a number of cellular bands. The combiner
incorporates high power internal components and an
integral heat sink to enable the device to combine non-
coherant 50 Watt signals. The housing and heat sink are
fabricated as one piece for optimum heat transfer and
low cost. The insertion loss, when combining
non-coherant signals, is a low -6.24dB nominal, only
0.22dB above the theoretical combining loss for a 4-way
device. Microstrip construction offers a design that is cost
effective and highly repeatable.

(Dimensions in parenthesis are in mm)
The required method of cooling is forced air at 45 CFM
at +60°C Max ambient for four 50 Watt simultaneous
inputs. If the input power level or ambient temperature
is lowered, the forced air requirement can be reduced.
This device can be provided with type N connectors or
different power handling capability. M/A-COM also offers
a wide selection of cost effective devices for combining
and dividing any number of channels in popular cellular
transmit and receive bands. Please consult our factory.
