Eudyna Devices Inc. Confidential
Features
Quad-band, true SP6T PHEMT switch with integrated
decoder and low pass filter
Low insertion loss solution over the frequencies from
824 to 960 MHz and 1710 to 1990 MHz with no
diplexer required
Low cost, plastic mold package
Small, low profile package: 4 x 4 x 0.85 mm3
Applications
Quad-band handset for GSM850/900 and
DCS1800/PCS1900
Description
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.
