Two-Way 0° Power Splitter Combiner 1.71–1.99 GHz PD19-73 Features ■ Low Cost SO T-6 ■ Low Profile SOT -6 ■ Available in Small SOT-6 Lead Package ■ Tape & Reel -6 SOT ■ Pin Compatible with PD09-73 SOT -6 Description The PD19-73 is a monolithic two-way in-phase hybrid junction tuned for the 1.71–1.99 GHz band. It offers low loss, high isolation, good input/output matching and exceptional phase/amplitude balance. It is available in the SOT-6 lead surface mount package. The PD19-73 was designed to be pin-to-pin compatible with the PD09-73 Power Splitter/Combiner. This allows similar board layout for Power Splitter/Combiners in the frequency ranges covering 810–960 MHz and 1.7–1.99 GHz. The PD18-73 also covers 1.71–1.99 GHz but with different pin connections.
