Product Description
Applications
TriQuint’s TQP4M3018 is a high power antenna switch in a single pole three throw
(SP3T) configuration. The die utilizes TriQuint’s PHEMT MMIC switch process to
provide optimized cross-modulation performance for use in CDMA applications.
PHEMT Switches are a very low DC current replacement for classic PIN diode
based switches. This product is ideally suited to applications where the antenna of
a CDMA handset is to be routed to the Cellular duplexer, the PCS duplexer and
the GPS receiver input. The design is symmetric and broadband allowing the user
to assign cellular, PCS and GPS to ports RF1, RF2 or RF3 as desired.
