28 GHz Analog Medium Output Voltage Driver
The Photline DR-AN-28-MO is a wideband RF 3-stages (inverting) amplifier module designed for analog applications at frequencies up to 20 GHz.
The Photline DR-AN-28-MO is characterized by a low Noise Figure and a linear transfer function whose 1 dB compression point is above 20 dBm. It exhibits flat Group Delay and Gain curves with reduced ripple over the entire bandwidth.
The Photline DR-AN-28-MO operates from a single power supply for safety and ease of use, and offers gain control over 3 dB. It comes in a compact housing with K type RF connectors (compatible SMA) and with an optional heat sink.
This amplifier module is ideally suited to drive optical modulators for analog applications.

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.
