4 Way Type N Power Divider Combiner

four way wilkinson power divider combiner with
precision designed and etched microstrip circuit


PD1040 is an RF broadband, 4 way, power divider, power combiner furnished with type-N female coaxial connectors. All wireless band frequencies from 0.698 - 2.700 GHz 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 4 way power divider input rating tables for 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). Electrical performance is highlighted by 0.8 dB max insertion loss (above the 6.02 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 4 way power divider test sweeps for specific details.


Mechanical features include precision CNC turned, brass, 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 maintained by

the rugged CNC machined aluminum housing with yellow iridite finish. Secure mounting is provided by two 0.125" diameter (3.18 mm) through holes.


Housing dimensions are 3.98" wide by 2.98" deep by 0.75" high (101.1 x 75.7 x 19.1 mm). The N-type female connectors extend 0.65" (16.5 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 386 grams. See 4 way power divider outline drawing for more information.


The PD1040 4-way, N-Type Female, 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.

Options / Additional Models

RoHS Compliant: A RoHS compliant version of this four way power divider is available with no-lead solder and a finish free of hexavalent chromium. PD2040

DC Blocking: Two DC blocking versions of this 4way divider combiner available:

PD5040: DC pass 1 port, DC block 3 ports. Typically used for powering an active antenna through the DC pass port of the RF power divider splitter.

PD5042: DC block 4 ports. Typically used in combining applications to prevent passing DC to sum port or other inputs.

GPS Splitter: 4-way GPS antenna signal splitter covering L1, L2, GLONASS and Galileo GNSS global navigation satellite system positioning frequency bands.

GPS400: Four 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.
