PD2730 - Features & Benefits

Overview

PD2730 is a RoHS compliant, 3 way, wideband, 50 ohm, RF power divider, power combiner furnished with QMA jack female coaxial connectors. 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 3 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. Electrical performance is highlighted by 0.6 dB max insertion loss (above the 4.77 dB power split), 22 dB min isolation, 1.30:1 max input VSWR and 1.25:1 max output port VSWR. Equal power split and symmetry is displayed by 0.2 dB amplitude balance and 3 degrees phase balance. Narrow band RF performance over your frequency range may be even better. See 3 way power divider test sweeps for details.

Mechanical

Mechanical features include precision CNC, brass, 50 ohm QMA 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" diameter (3.18 mm) through holes. RoHS construction includes no-lead solder and a finish free of hexavalent chromium.

Physical

Housing dimensions are 2.98" wide by 2.98" deep by 0.88" high (75.7 x 75.7 x 22.2 mm). The QMA female (jack) connectors extend 0.56" (14.3 mm) from the housing. Operating temperature range is from -65°C to +85°C. Weight is 294 grams. See 3 way QMA splitter outline drawing for more information.

Applications

The PD2730 3-way, QMA-jack, 698-2700 MHz power 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
