PD508B Features & Benefits
PD508B is an 8 way N-type power divider operating from 698-2700 MHz and blocking DC+10 MHz from eight (8) ports. This passive Wilkinson microstrip unit equally splits the full L-band radio spectrum between two receivers or modems while blocking DC and 10 MHz from both ports. This model is ideal for satellite and VSAT applications splitting the down converted L-band signal equally between two receivers or modems in cases where DC current and the 10 MHz reference signal must be blocked from, respectively, the LNB and BUC. With integrated filters, the 10 MHz signal is rejected by more than 50 dB without affecting integrity of signals in the L-band spectrum. This unit is rated to withstand 50VDC. All L-band applications in the frequency range from 698 to 2700 MHz are covered with best in class performance.
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, 1.40:1 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 features include precision CNC, brass, 50 ohm N type female coaxial connectors with tri alloy plating to insure tarnish resistance and low PIM operation. 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 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 7.750" wide by 202.7" deep by 0.88" high (196.85 x 202.7 x 22.2 mm). The N type female (jack) connectors extend 0.65" (16.3 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 864 grams. See 8 way L-band splitter outline drawing for more information.
The PD508B 8 way, type N jack, DC+10 MHz blocking, L-band splitter 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.
