PD19-73
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.
