PD16-73
Description
The PD16-73 is a monolithic two-way in-phase hybrid
junction tuned for the 1.42–1.66 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 footprint of the
PD16-73 is the same as the other power dividers in this
package style and series to allow for consistent assembly
setup.
