- For S-Band Pulsed Radar Application
• Easy To Use – 50 Ω Plug-and-Play
• Reduce Design Cycle Time
• Improve System Performance
• Reduce System Size and Components
GENERAL DESCRIPTION
The 2731-200P is a 50 ohm matched Power Solution Module (PSM), consists of two common base
high power transistors, for S-Band pulsed Radar systems. This PSM is capable of providing 200 Watts
of pulsed RF output power at two hundreds microsecond pulse width ten percent duty factor across
2700-3100 MHz. This PSM is designed with the plug-n-play concept which is extremely user friendly
and requires no additional tuning and impedance matching from the customer.
Mechanical Size is 2” x 1.41” x 0.21”
