Description
M/A-COM鈥檚 PD60-0008-02S is designed to provide a
low loss method of combining signals from two trans-
mitters at PCS frequencies. High power internal compo-
nents and an integral heat sink enables the device to
combine non-coherant 20 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 -3.17dB nomi-
nal, only 0.15dB above theoretical loss for a 2-way
device. Microstrip construction offers a design that is
cost effective and highly repeatable.

The required method of cooling is forced air at 10 CFM
at +60擄C Max ambient for two 20 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
increased 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 con-
sult our factory.
