PD60-0011-05S is designed to provide a low loss method of combining signals from ?e ampli?rs or transmitters at pcs frequencies. high power internal components and an integral heat sink enables the device to combine non-coherant 20 watt signals. microstrip construction offers a design that is cost effec- tive and highly repeatable. *above 7db theoretical combining loss the required method of cooling is forced air at 25 cfm at +60? max ambient, for five 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 consult our factory. sma jack (6 pls) j6 j5 j4 j3 j2 j1 thru 2.25 (57.2) .38 (9.5) .75 (19.1) 6.00 (152.4) .15 (3.8) 4.50 (114.3) .15 (3.8) 5.70 (144.8) 4.20 (106.7) 1.38 (34.9) nom .75 (19.1) typ .16 (4.0) 4x preliminary speci?ations parameter limit typical impedance 50 ohms nom vswr 1.35:1 max 1.15:1 insertion loss* 0.8db max 0.5db amplitude balance 0.3db max 0.15db isolation 20db min 24db max input power 20 watts/input operating temp -40 to +60? performance speci?ations: 1930-1990 mhz (dimensions in parenthesis are in mm)
