Solder Recommendations
The HPMD-7904 FBAR duplexer (and its variants) is
an assembly consisting of two LCC ceramic packages,
containing the Tx and Rx filters, mounted to a small
circuit board. Both packages on the circuit board are
mounted in place using Sn96.5/Ag3.5 solder (shaded
in Table 1).

The recommended solder profile for the FBAR
duplexer is shown in Figure 16. Guidelines and a
typical profile are both shown. This typical profile
was tested on ten samples of the duplexer, each of
which was subjected to the profile six times without
effect upon the mechanical or electrical characteris-
tics of the device. Solder temperatures and times in
excess of those given in the guidelines of Table 1 may
result in damage to the duplexer or changes in its
characteristics.
