P-20A
• 15 ps risetime
• Compact 3-pin package
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
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-pulse
TM
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.

Application Notes
Electrostatic discharge (ESD) will cause permanent
damage to the product. Please avoid any ESD to the
input pins or output connector. Use standard ESD
protective equipment when handling this product.
Temperature and fiber restrictions are as follows:
Lead soldering: 250°C for no more than 10 seconds
Fiber feed-through tube: 120°C
Fiber pull force: 10 N
Fiber bending radius: 1 inch or less
Exceeding these conditions can cause permanent
damage to the device.
