Water and Weather Resistant 3 Way Power Splitter Combiner

IP67 weather resistant splitter for outside use
3 way type N female power splitter combiner


PD2031 is an outdoor, IP67 water and weather resistant, 3 way, wideband, 50 ohm, power divider, power combiner furnished with type N female jack coaxial connectors. All wireless band applications in the frequency range from 698 to 2700 MHz are covered with best in class RF 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 more information.


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 RF power divider, power combiner with equal power split and balance, the PD2031's electrical performance is highlighted by 0.7 dB max insertion loss (above the -4.77 dB power split), 18 dB min isolation, 1.35:1 max input VSWR and 1.25:1 max output VSWR. Equal power split and balance is displayed by 0.2 dB max amplitude balance and 3 degrees max phase balance. Narrow band RF performance over your frequency range may be even better. See 3 way Type N Female power divider test sweeps for specific details.


Mechanical features include precision CNC, brass, 50 ohm N type female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. Connector pins are gold-plated 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 passivated finish. Provision for secure mounting is provided by two .125" diameter (3.18 mm) through holes. RoHS construction includes no-lead solder and finish free of hexavalent chromium. Water and weather resistance for uninterrupted safe outdoor use is is achieved through silicone o-rings sealing all components.


Exterior housing dimensions are 3.28" wide by 3.28" deep by 1.00" high (83.3 x 83.3 x 25.4 mm). The type N connectors extend 0.65" (16.5 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 480 grams. Rated for continuous water and weather resistant exterior use. May also be used indoors. See 3 way power divider outline drawing for more details.


The PD2031, IP67 weatherproof, three way, type N female, RF power divider (splitter) combiner is ideal for a broad range of outdoor wireless radio frequency microwave applications on both transmit and receive sides, ranging from amplifier sharing & receiver combining 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.

Options / New Outdoor Units

Indoor Model: An indoor version of this three (3) way power combiner divider is available with RoHS construction. PD2030

DC Blocking: Two DC blocking versions of this IP67 outdoor 3way divider combiner:

PD5031: DC pass one port, DC block two ports. Typically used for powering an active antenna through the DC pass port of the outdoor RF power divider splitter.

PD5033: DC block 3 ports. Typically used in combining applications to prevent passing DC current to sum or other ports.

GPS Splitter: 3-way GPS antenna signal splitter covering L1, L2, GLONASS and Galileo GNSS global navigation satellite system positioning frequency bands.

GPS301: Three way GPS signal splitter, DC pass one port - providing a means to power an active GPS antenna - other ports DC blocked and furnished with 200 ohm internal loads to simulate antenna preamp current draw, preventing the GPS receiver from sensing antenna fault.
