P-18A Datasheet, PDF (1/2 Pages) Advanced Photonix, Inc. – An ultrafast, InGaAs PIN photodetector

P-18A
Product Bulletin (Preliminary) • February 2002
• PIN detector module
• 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.
