RP2140 is a reverse-polarity SMA jack, RoHS compliant, 4 way, wideband, 50 ohm, RF power splitter, power combiner ideally suited for 2.4 GHz Wi-Fi and wireless LAN & WAN communications applications using the IEEE 802.11 protocol. All wireless band frequencies in the range from 698 to 2700 MHz are covered with optimal RF 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 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. 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 divider test sweeps 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
Housing dimensions are 3.98" wide by 2.98" deep by 0.88" high (101.1 x 75.7 x 22.2 mm). The RP-SMA 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 divider outline drawing for more information.
The RP2140 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 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.
Standard Model: A standard version of this four way power combiner divider is available with SMA jack connectors and construction utilizing tin/lead solder and comprising a yellow iridite finish. PD1140
PD5140: DC pass 1 port, DC block other ports. Typically used for powering an active antenna through the DC pass port of the RF power divider splitter.
PD5142: DC block 4 ports. Typically used in combining applications to prevent passing DC to sum port or other input.
GPS Splitter: 3-way GPS antenna signal splitter covering L1, L2, GLONASS and Galileo GNSS global navigation satellite system positioning frequency bands.
GPS410: 4 way SMA GPS signal splitter, DC pass one port - providing a means to power an active GPS antenna - other ports DC blocked and furnished with a 200 ohm internal load to simulate antenna preamp current draw, thus preventing the GPS receiver from sensing antenna fault.
