P-20A
Product Bulletin (Preliminary) • February 2002
• 14 GHz PIN detector module
• Front-end for receivers up to 12.5 Gb/s
• High responsivity, 1.0 A/W
• 15 ps risetime
• Compact 3-pin package
The P-20A is an ultrafast, InGaAs PIN
photodetector module ideal for use as an
O/E front-end for receivers in applications
up to 12.5 Gb/s. The back-illuminated
PIN photodiode design optimizes speed
and sensitivity for the 1200 nm through
1650 nm wavelength range. The internal
Clean-pulseTM design assures low group-
delay response necessary for time-domain,
digital applications.
The detector is available in a compact
3-pin package with either an Anritsu-K
output connector or an RF feed-through
pin for direct soldering to circuit boards.
Input via a single-mode fiber is standard.
The hermetic module is Telcordia
compliant.
