HPMD-7905 Datasheet, PDF (5/8 Pages) Agilent(Hewlett-Packard) – FBAR Duplexer for US PCS Band

Note that the specifications given
on page 2 are guaranteed when
the duplexer is mounted on a
ground surface with a hole
pattern like that one shown in
Figure 11. See Design Note D007,
which is available from your
Agilent Technologies technical
support or sales departments.
Note that it is important that
proper heat sinking be provided
in order to remove the heat
generated in the Tx filter by the
handset’s power amplifier.
Failure to do so may result in
excessive losses, especially at the
top end of the Tx band.
