HIGH POWER CW MICROWAVE AMPLIFIER
- SPECIFICATIONS -



MODEL 9820/95300-J17J18

200 Watt, CW, 17.6 - 18.4 GHz

Dedicated Amplifier System Series 9820



Series 9820 Amplifier Systems provide the maximum in reliability, cost effectiveness and convenience. This state-of-the-art product delivers high performance for benign laboratory or hostile field environments.

Microprocessors provide the operator, and or computer, access to monitor TWT conditions, fault latching, and control of the power supply for both the safety of the TWT and the operator. These controls also provide a TWT warm-up delay, automatic sequencing of High Voltage and Beam Current as well as an automatic recycle feature.

OPTIONS
OPTION 50 - RACK MOUNTING
Allows the unit to be mounted in a standard EIA 19 inch rack cabinet, incorporating side mounted slides.
OPTION 40 - 400 Hz
Provides for 400 Hz AC frequency operation
OPTION 01 - OUTPUT ISOLATOR
Protects the TWT from varying load VSWR conditions. Insertion loss of the Isolator may lower the output power slightly (0.5 dB typically) from normal. Call the factory for configuration and dimensions. (Isolator may be provided externally)
OPTION 20 - REFLECTED POWER PROTECTION
Protects the TWT from high load VSWR and is intended for use on ultra wide band or high power units for which Isolators are not normally available. Consists of a coupler and detector that turns the TWTA off when excessive reflected power is sensed. Typical insertion loss is 0.5 dB.
