PD2803 - Features & Benefits
PD2803 is a RoHS compliant, 3 way, wideband, 50 ohm, RF power divider, power combiner furnished with N-jack (female) coaxial connectors with an N-plug (male) input connector. All wireless band frequencies in the range from 698 to 2700 MHz are covered with optimal 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 additional details. The special feature of this unit is the N-Type male and female coaxial connectors, making it directly insertable into your RF transmission path. This minimizes VSWR and insertion loss by eliminating the need for additional adapters and special cables in your transmission line.
The heart of the unit is a precision designed and etched Wilkinson type microstrip circuit on a low loss, high frequency, dielectric substrate. Electrical performance is highlighted by 0.4 dB max insertion loss (above the 4.77 dB power split), 22 dB min isolation, 1.20:1 max input VSWR and 1.15:1 max output port VSWR. Equal power split and symmetry is displayed by 0.2 dB amplitude balance and 2 degrees phase balance. Narrow band RF performance over your frequency range may be even better. See 3 way power divider test sweeps for details.
Mechanical features include precision CNC, brass, 50 ohm N-type 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 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 1.98" wide by 1.98" deep by 0.88" high (50.3 x 50.3 x 22.2 mm). The N-type female (jack) connectors extend 0.65" (16.3 mm) from the housing. The N-type male (plug) connector extends 0.89" (22.4 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 189 grams. See 3 way N-type splitter outline drawing for more information.
The PD2803 3-way, N-type jack, 698-2700 MHz power splitter combiner with N-type plug common port (sum) 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 / Additional Models
N-Type Female : A standard version of this three way power combiner divider is available furnished with Type N female (jack) connectors on all ports. PD2030
DC Blocking: Two DC blocking versions of this 3way divider combiner available:
PD5030: DC pass 1 port, DC block other ports. Typically used for powering an active antenna through the DC pass port of the RF power divider splitter.
PD5032: DC block 3 ports. Typically used in combining applications to prevent passing DC to sum port or other input.
GPS Splitter: 3-way GPS antenna signal splitter covering L1, L2, GLONASS and Galileo GNSS global navigation satellite system positioning frequency bands.
GPS300: 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 a 200 ohm internal load to simulate antenna preamp current draw, thus preventing the GPS receiver from sensing antenna fault.
