MODEL 9820/95100-K27K30

120 WATT, CW, 27.5 - 29.5 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
OPTIONS E - RACK MOUNTING
Allows the unit to be mounted in a standard EIA 19 inch rack cabinet, incorporating side mounted slides.
OPTION G - 400 Hz
Provides for 400 Hz AC frequency operation
OPTION J - OUTPUT ISOLATOR
Protects the TWT from varying load VSWR conditions. Insertion loss of the Isolator will lower the output power slightly (0.5 dB typically) from normal. Call the factory for configuration and dimensions. (Isolator may be provided externally)
OPTION X - 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.
