Description
Lead Free
4 mm x 4 mm x 0.85 mm
Module Package
The
FMM5321ZV
is a miniature
4 mm x 4 mm quad-
band GSM850/900, DCS1800, PCS1900
antenna switch
module that utilizes Eudyna’s highly reliable
PHEMT
technology for Europe/US
GSM and GPRS
handsets and wireless communication systems. The true SP6T PHEMT switch does not require a
diplexer, the component that causes additional insertion loss and yield degradation. The frequency
response is determined by built-in low pass filters, which simplify impedance matching with a power
amplifier.
