Description
The RFP-375375A6Z50 is a high performance Alumina (Al2O3) surface
mount termination intended as a lower cost alternative to Aluminum
Nitride (AIN) and Beryllium Oxide (BeO). The SMD termination is well
suited to all cellular frequency bands such as: AMPS, GSM, DCS, PCS,
PHS and UMTS. The high power handling makes the part ideal for
terminating 90 hybrids, directional couplers, and for use in isolators.

For best thermal performance the PCB should be soldered to
the heat sink.
RFP-375375
1. Drill thermal vias through PCB and fill with solder, such as SN63 type.
2. Solder part in place using SN63 type solder with controlled temperature iron
(700F).
3. To ensure good thermal connectivity to heat sink, which is critical for proper
operation drill and tap heatsink and mount PCB board to heat sink using screws.
