DATA SHEET PD18-73/PD18-73LF: 1.71-1.99 GHz Two-Way 0 Power Splitter/Combiner Applications Signal distribution/combining GSM, WCDMA, PCS/DCS Features Low cost Low profile Small SOT-6 package (MSL1, 260 C per JEDEC J-STD-020) Figure 1. PD18-73/PD18-73LF Block Diagram Description The PD18-73/PD18-73LF are monolithic, two-way in-phase hybrid junction power splitter/combiners for the 1.71 to 1.99 GHz band. Either device offers low loss, high isolation, good input/output matching, and exceptional phase/amplitude balance. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2.

PD18-73/PD18-73LF Absolute Maximum Ratings (Note 1) Parameter Symbol Minimum Maximum Units RF input power, CW (Note 2) PIN 1.5 W RF input power, CW (Note 3) PIN 0.75 W Operating temperature TOP 40 +85 C Storage temperature TSTG 65 +150 C Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. Note 2: When used as a power divider with a 2.0:1 maximum VSWR on all ports. Note 3: When used as a power combiner with a 2.0:1 maximum VSWR on all ports. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
