PD60-0003-04S is designed to provide a low loss method of combining signals from four trans- mitters at pcs frequencies. high power internal compo- nents and an integral heat sink enables the device to combine non-coherent 25 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-coherent signals, is a low -6.27db nomi- nal, only 0.25db above theoretical loss for a 4-way device. microstrip construction offers a design that is cost effective and highly repeatable. *above 6db theoretical combining loss the required method of cooling is forced air at 35 cfm at +60? max ambient, for four 25 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. j1 j2 j3 j4 j5 finned heat sink sma jack (5 pls) 3.50 .50 (12.7) 2.75 (69.9) .15 (3.8) 1.75 (44.5) 5.50 (139.7) 5.20 (132.1) .19 (5) 1.00 (25.4) 1.50 (38.1) typ .144 (3.7) 2x thru
