Microwave PIN Photodiode Receivers
The Ortel family of microwave photodiode receivers is ideally suited for
use in analog fiber-optic communications. With their wide bandwidth
and flat response, these devices are used in a wide array of
applications, including antenna remoting, timing and reference signal
distribution, measurement, delay lines, and two-way communications.
Several packaging styles are available for these microwave
photodiodes. The most basic package, the photodiode module, contains
the photodiode chip, optical fiber pigtail, and impedance-matched
electrical connections in a hermetically sealed unit. Of particular note is
the high optical return loss, which enables high-quality noise
performance for sensitive optical links.
Applications
Antenna Remoting
Cellular and PCS networks
Military triband
communications
Tracking, Telemetry and
Control (TT&C)
In most cases, the basic photodiode module is integrated into a
complete receiver, packaged either as a flange-mount for extreme
environments, or as a plug-in for integration with Ortel’s System 10000
rack-mountable chassis and power supplies. Electronics within flange-
mount and plug-in receivers bias the photodiodes and monitor the dc
level of the optical input power, thus providing a fully integrated
microwave product.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.
