DC Block Power Divider Combiner, 8 Way, SMA Jack

8 way, SMA, DC blocking RF splitter combiner
ideal for 1-2 GHz L band satellite applications

Overview

PD5180 is an 8 way, passive, 50 ohm, DC blocking RF power divider, power combiner with SMA connectors passing DC one port and blocking DC seven ports. The pass port passes RF, 10 MHz and DC. The blocked ports pass 10 MHz and RF but block DC current. Maximum voltage rating at the DC blocked ports is 50 VDC. All wireless band applications in the 698 to 2700 MHz and L Band frequency range covered with best in class performance. The RoHS compliant, bidirectional PD5180 is capable of handling input power levels up to 40 watts in both power splitter and power combiner applications. See 8 way power divider input rating tables for info.

Electrical

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 1.3 dB max insertion loss (above the -9.03 dB power split), 22 dB min isolation, 1.35:1 max input VSWR and 1.20:1 max output port VSWR. Equal power split and symmetry is displayed by 0.5 dB amplitude balance and 6 degrees phase balance. Narrow band RF performance over your frequency range may be even better. See 8 way power divider test sweeps for details.

Mechanical

Mechanical features include precision CNC, brass, 50 ohm 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 cable mating. Long term operation and superior shielding is assured by the rugged CNC machined aluminum housing with clear chemical film finish. Mounting is provided by four 0.125" dia (3.18 mm) thru holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.

Physical

Housing dimensions are 7.98" wide by 2.98" deep by 0.88" high (202.7 x 75.7 x 22.2 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 740 grams. See 8 way RF power divider outline drawing for more information.

Applications

The PD5180, 8 way, SMA female, DC blocking power 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.
