PD2578 Features & Benefits


PD2578 is an IP67 weatherproof, RoHS compliant, 3 way, wideband, 50 ohm, power divider, power combiner furnished with SMA female coaxial connectors. All wireless band applications in the frequency range from 2400 to 6000 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 4 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). Electrical performance is highlighted by 1.0 dB max insertion loss (above the 6.02 dB power split), 20 dB min isolation, 1.45:1 max input VSWR and 1.30:1 max output VSWR. Equal power split and balance is displayed by 0.3 dB max amplitude balance and 5 degrees max phase balance. Narrow band RF performance over your frequency range may be even better.


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 and phosphor bronze for reliability and low contact resistance. Virgin electrical grade PTFE support insulators captivate the contact pins enabling trouble free coaxial connector mating. Long term operation and superior shielding is assured by the rugged CNC machined aluminum housing with clear chemical film finish. Secure mounting is provided by two 0.125" diameter (3.18 mm) through holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.


Housing dimensions are 4.08" wide by 1.98" deep by 0.88" high (103.6 x 50.3 x 22.2 mm). The SMA female connectors extends 0.44" (11.1 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 314 grams. Rated for continuous water and weather resistant exterior use. May also be used indoors. See 4 way power divider outline drawing for more information.


The PD2578 4-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 IEEE802.11b/g, 2.45 GHz ISM, Wi Fi, 2.3 GHz & 2.5 GHz WiMAX, and 4G LTE.
