three way wilkinson RF power divider combiner
T-Housing allows convenient coax cable access

Overview

PD4030 is a RoHS compliant, 3 way, wideband, 50 ohm power divider, power combiner furnished with N-type female coaxial connectors in a T-Style housing. All wireless band frequencies in the 700 to 2700 MHz 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 more detail.

Electrical

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 PD4030's electrical performance is highlighted by 0.7 dB max insertion loss (above the -4.77dB power split), 22 dB min isolation, 1.35:1 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 N type female power divider test sweeps for specific details.

Mechanical

The PD4030's T-Style housing allows convenient RF cabling access to all

connector ports. Featuring precision CNC turned, brass, 50 ohm type-N female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. Coaxial 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 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" dia (3.18 mm) through holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.

Physical

Housing dimensions are 1.98" wide by 2.98" deep by 0.88" high (50.3 x 75.7 x 22.2 mm). The type N female (jack) connectors extend 0.65" (16.5 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 251 grams. See 3 way power divider outline drawing for more information.

Applications

The PD4030 3-way, N 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 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

Standard Model: A standard version of this three way power combiner divider is available utilizing tin/lead solder and comprising a yellow iridite finish. PD3030

DC Blocking: Two DC blocking versions of this 3way RF splitter combiner available:

PD7030: DC pass 1 port, DC block 2 ports. Typically used for powering an active antenna through the DC pass port of the 3 way RF power divider splitter.

PD7032: DC block 3 ports. Typically used in combining applications to prevent passing DC to sum port or other inputs.
