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.
