PD3130 Features & Benefits


PD3130 is an RF broadband, 3 way, power divider, power combiner furnished with SMA female (jack) coaxial connectors in a T-Style housing. All wireless band frequencies in the 0.698 to 2.700 GHz range are covered with optimal performance. Max microwave input power levels up to 40 watts can be handled in both power splitter and power combiner applications. See 3 way power divider input rating tables for specific details.


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 3 way power divider, power combiner with equal power split and balance, the PD3130's electrical performance is highlighted by 0.7 dB max insertion loss (above the 4.77 dB power split), 22 dB min isolation, 1.30:1 max input VSWR and 1.15:1 max output VSWR. Equal power split and balance is displayed by 0.3 dB max amplitude balance and 4 degrees max phase balance. Narrow band RF performance over your frequency range may be even better. See 3 way SMA female power divider test sweeps for specific details.


The PD3130's T-Style housing allows convenient cable access to all coaxial connector ports. Mechanical features include precision CNC turned, brass, 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 connector mating. Long term operation and superior shielding is maintained by the rugged CNC machined aluminum housing with yellow iridite finish. Secure mounting is provided by two 0.125" dia (3.18 mm) through holes.


Housing dimensions are 1.98" wide by 2.98" deep by 0.75" high (50.3 x 75.7 x 19.1 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 163 grams. See 3 way power divider outline drawing for more information.


The PD3130 3-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.
