P-18A
• PIN detector module
Product Bulletin (Preliminary) • February 2002
• Flat frequency response,
±
1 dB
• High responsivity, 0.9 A/W
• High bandwidth, 19 GHz
• Low VSWR
• Compact 3-pin package
The
P-18A
is an ultrafast, InGaAs PIN
photodetector that is ideal for use in
O/E front-ends requiring flat frequency
response. The back-illuminated photodiode
design optimizes speed and sensitivity for
the 1200 nm through 1650 nm wavelength
range. The internal waveguide design
assures a flat frequency response necessary
for analog applications.
The detector is available in a compact
3-pin package with either a 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.
