PD2316 - Features & Benefits


PD2316 is a RoHS compliant, 16 way, wideband, 50 ohm, RF power divider, power combiner furnished with N Type jack female coaxial connectors. All wireless band frequencies in the range from 350 to 1000 MHz are covered with optimal RF performance. Max microwave input power levels up to 30 watts can be handled in both power splitter and power combiner applications. See 16 way power divider input rating tables for additional details.


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 1.8 dB max insertion loss (above the 12.04 dB power split), 20 dB min isolation, 1.50:1 max input VSWR and 1.20:1 max output port VSWR. Equal power split and symmetry is displayed by 0.6 dB amplitude balance and 8 degrees phase balance. Narrow band RF performance over your frequency range may be even better. See 16 way power divider test sweeps for details.


Mechanical features include precision CNC, brass, 50 ohm Type N female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. Connector pins are gold plated phospher 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 chemical film finish. Secure mounting is provided by four 0.125" diameter (3.18 mm) through holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.


Housing dimensions are 15.98" wide by 3.48" deep by 0.88" high (405.9 x 88.4 x 22.2 mm). The N female (jack) connectors extend 0.65" (16.3 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 1920 grams. See 16 way N-type splitter outline drawing for more information.


The PD2316 16-way, N-jack, 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.
