DESCRIPTION

Microsemi’s GaAs Coplanar PIN

Photo Diode chips are ideal for high

bandwidth 850nm optical networking

applications.

The device family offers superior

noise performance and sensitivity in

single die, 1x4 array die or 1x12 array

die.

The LX304X family of photo diodes

are

currently

offered

in

die form

allowing manufacturers the versatility

of custom assembly using either bond

wire or flip chip configurations.

This

device

is

ideal

for

manufacturers

of

optical

receivers,

transponders,

optical

transmission

modules and combination PIN photo

diode – transimpedance amplifier.
