PD2120 - RF Power Splitter, Combiner, Divider
RoHS, 2 Way, SMA Female, 700 - 2700 MHz, 50 Ohms
Features & Benefits
two way SMA Wilkinson RF power splitter
featuring RoHS compliant construction
Overview
PD2120 is a RoHS compliant, 2 way, wideband, 50 ohm, RF power divider, power combiner furnished with SMA female coaxial connectors. All wireless band frequencies in the range from 700 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 2 way power divider 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 0.4 dB max insertion loss (above the -3.01dB 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 2 degrees max phase balance. Narrow band RF performance over your frequency range may be even better. See 2 way power divider 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
Physical
Housing dimensions are 1.98" wide by 1.98" deep by 0.88" high (50.3 x 50.3 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 133 grams. See 2 way power divider outline drawing for more information.
Applications
The PD2120 2-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.
Options / Additional Models
Standard Model : A standard version of this two way power combiner divider is available utilizing tin/lead solder and comprising a yellow iridite finish. PD1120
DC Blocking: Two DC blocking versions of this 2way divider combiner available:
PD5120: DC pass 1 port, DC block other port. Typically used for powering an active antenna through the DC pass port of the RF power divider splitter.
PD5122: DC block 2 ports. Typically used in combining applications to prevent passing DC to sum port or other input.
GPS Splitter: 2-way GPS antenna signal splitter covering L1, L2, GLONASS and Galileo GNSS global navigation satellite system positioning frequency bands.
GPS210: 2 way SMA GPS signal splitter, DC pass one port - providing a means to power an active GPS antenna - other port DC blocked and furnished with a 200 ohm internal load to simulate antenna pre-amp current draw, thus preventing the GPS receiver from sensing antenna fault.
