High Power, 4 Channel PCS Transmit Combiner 1930 - 1990 MHz PD60-0003-04S V2.00 Features ● ● J2 5.50 (139.7) 2.75 (69.9) .50 (12.7) 1.00 (25.4) SMA JACK (5 PLS) J3 ● .144 THRU (3.7) .19 (5) 5.20 (132.1) Description M/A-COM’s PD60-0003-04S is designed to provide a low loss method of combining signals from four transmitters at PCS frequencies. High power internal components 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 nominal, only 0.25dB above theoretical loss for a 4-way device. Microstrip construction offers a design that is cost effective and highly repeatable. 1.50 TYP (38.1) J4 ● Low Loss High Power Handling Integral Heat Sink High Isolation Low VSWR Low Cost 2X J5 ● 1.75 (44.5) J1 ● .15 (3.8) 3.50 FINNED HEAT SINK (Dimensions in parenthesis are in mm) The required method of cooling is forced air at 35 CFM at +60°C 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.
