Use the PD2140 to connect up to four devices to a single High-Gain Antenna. This antenna combiner is supplied complete with 4 x 1m long pre-terminated low loss cables with SMA Male connectors to help ensure a hassle free installation. - Wideband Frequency (700 - 2700 MHz) - Low Insertion Loss (0.4 dB avg) - High Port to Port Isolation (30 dB avg) - Excellent VSWR (1.10 : 1 avg) - RoHS Compliant Splitter Construction - Tri Alloy SMA Female (Jack) 50 Ohm - Supplied with 4 x 1m long connection cables (SMA Male Connectors) PD2140 is a RoHS compliant, 4 way, wideband, 50 ohm, power divider, power combiner furnished with SMA jack (female) coaxial connectors. All wireless band applications in the 700 to 2700 MHz frequency range are covered with optimal performance. Max microwave input power levels up to 40 watts can be handled in both power splitter and power combiner applications. See 4 way power splitter input rating tables for additional details. Electrical 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. Power splitter dividers passing DC to select ports and blocking DC to others are also available. See options (right). Electrical performance is highlighted by 0.8 dB max insertion loss (above the -6.02 dB power split), 22 dB min isolation, 1.25:1 max input VSWR and 1.15:1 max output VSWR. Equal power split and balance is displayed by 0.2 dB max amplitude balance and 4 degrees max phase balance. Narrow band RF performance over your frequency range may be even better. See 4 way power splitter test sweeps for specific 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 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" dia (3.18 mm) through holes. RoHS compliant construction includes no-lead solder and a finish free of hexavalent chromium. Physical Housing dimensions are 3.98" wide by 2.98" deep by 0.88" high (101.1 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 383 grams. See 4 way power splitter outline drawing for more information. Applications The PD2140 4-way, SMA female (jack), power divider (splitter) combiner is ideal for a wide range of wireless radio frequency microwave applications on both transmit and receive sides, ranging from amplifier combining & receiver dividing 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.
