PD2412 Features & Benefits


PD2412 is a RoHS compliant, 12 way, wideband, 50 ohm, power divider, power combiner furnished with SMA female coaxial connectors. All wireless band applications in the frequency range from 1000 MHz are covered with optimal performance. Max microwave input power levels up to 30 watts can be handled in both power splitter and power combiner applications. See 12 way power divider input rating tables for more detail.


The heart of the unit is a precision designed and etched Wilkinson type microstrip circuit on a low loss, high frequency, dielectric substrate. The Wilkinson microstrip circuit passes DC current to all ports making it ideal for use in active systems. Power splitter dividers passing DC to select ports and blocking DC to others are also available. See options (right). A true 12 way power divider, power combiner with equal power split and balance, the PD2412's electrical performance is highlighted by 1.4 dB max insertion loss (above the -10.79dB power split), 18 dB min isolation, 1.45:1 max input VSWR and 1.25:1 max output VSWR. Equal power split and balance is displayed by 0.4 dB max amplitude balance and 7 degrees max phase balance. Narrow band RF performance over your frequency range may be even better. See 12 way SMA female power divider test sweeps for specific details.


Mechanical features include precision CNC, brass, 50 ohm SMA female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. Connector pins are gold plated beryllium copper for reliability and low contact resistance. Virgin electrical grade PTFE support insulators captivate the contact pins enabling trouble free coaxial mating. Long term operation and superior shielding is assured by the rugged CNC machined aluminum housing with clear chemical film finish. Mounting is provided by four 0.15" dia (3.81 mm) thru holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.


Housing dimensions are 11.75" wide by 4.48" deep by 0.88" high (304.3 x 113.8 x 22.2 mm). The SMA female (jack) connectors extend 0.44" (11.1 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 1467 grams. See 12 way power splitter outline drawing for more information.


The PD2412 12 way, SMA female (jack), power divider (splitter) combiner is ideal for a wide range of wireless radio frequency microwave applications on both transmit and receive sides, ranging from amplifier combining & receiver dividing to antenna splitting, and is deployed world wide in networks encompassing 700 MHz Public Safety Band, 800 MHz cellular, GSM 850, 900, 1800 & 1900, PCS 1900, 1 GHz to 2 GHz L-Band, GPS, W-CDMA-3G, UMTS, TETRA, RFID, IEEE802.11b/g, 2.45 GHz ISM, Wi Fi and 2.3 GHz & 2.5 GHz WiMAX.
