PD9126 - Features & Benefits


PD9126 is an outdoor, waterproof and weather resistant, IP67 rated, 2 way, 50 ohm, broadband RF high-power power combiner furnished with SMA female coaxial connectors. All wireless band frequencies in the range from 430 to 470 MHz are covered with best in class RF performance. Max microwave input power levels to 150 watts can be handled in power divider splitter applications. For non-coherent signals, up to 5 watts can be handled through each port. With coherent signals, up to 75 watts can be handled through each port. See 2 way high power combiner input rating tables for more info.


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. Electrical performance is highlighted by 0.2 dB typical insertion loss (above the 3.01 dB power split), 25 dB port-to-port isolation, 1.15 : 1 input VSWR and 1.10 : 1 output VSWR. Equal power split and balance is displayed by 0.1 dB avg amplitude balance and 2 degrees max phase balance. Narrow band RF performance over your frequency range may be even better. See 2 way power combiner test sweeps or high power combiner spec tables for specific details.


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 coaxial connector mating. Long term operation and superior shielding is assured by

the rugged CNC machined aluminum housing with clear passivated finish. Provision for secure mounting is enabled by four .203" diameter (5.16 mm) through holes. RoHS construction includes no-lead solder and finish free of hexavalent chromium. Water and weather resistance for uninterrupted safe outdoor use is achieved through silicone o-rings sealing all components.


Exterior housing dimensions are 2.58" wide by 2.78" deep by 1.00" high (65.5 x 70.6 x 25.4 mm). 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 287 grams. Rated for continuous water and weather resistant exterior use. May also be used indoors. See 2 way power combiner outline drawing for more details.


The PD9126, IP67 weatherproof, two way, SMA female, RF power combiner divider is ideal for a broad range of outdoor 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.
