Description
M/A-COM's DP52-0002 is an IC-based monolithic diplexer in a
low cost SOIC-8 SMT plastic package. This diplexer is ideally
suited for applications where small size, low insertion loss, supe-
rior repeatability and low cost are required. Typical applications
include AMPS/PCS and GSM/DCS dual mode portable devices.
The DP52-0002 is fabricated using a passive-integrated circuit
process. The process features full-chip passivation for increased
performance and reliability.
