-AGC                                   Automatic Gain Control is available to increase
                                                    the dynamic range in a wide variety of microwave
                                                    systems. AGC can be controlled by manual control,
                                                    voltage control, or binary input.

        -FIL                                     Filters can be integrated into the amplifier to attenuate
                                                    adjacent or harmonically related signals. Types of filters
                                                    available include Bandpass, Highpass, and Lowpass.

        -LIM                                    Limiters can be included to protect input stage from
                                                    CW signals to 25 dBm typical.

        -TC                                      Temperature Compensation is used to reduce gain change
                                                    over frequency.

        None                                   Hermetic Sealing is laser welding available for hermeticity,
                                                    to be used primarily for compliance with military standard
                                                    MIL-STD-8883 method 1014 for fine and gross leak testing.

        None                                   Coupled Ports are auxilliary output ports which can be
                                                    included for power measurements, monitoring, and for
                                                    AGC loops.

        -DET                                    Internal RF detectors can be included for output power level
                                                    verification.

        -TTL                                    Digital TTL levels are used to place amplifier in stand-by mode,
                                                    to reduce power consumption, and to provide better isolation.

        -BIT                                     A warning indicator as a Built In Test is used to signal
                                                    catastrophic failure in an amplifier by monitoring device current.

        -PS                                     A Power Supply is incorporated into an amplifier to accept a
                                                    wide variety of input voltages.

        -RM                                    Rack Mounted casings are available for most of MSI's model
                                                   amplifiers. These units include AC/DC power supply, forced
                                                   cooling if requierd, AC line filtering, and circuit breaker.

        -C                                       A Class C amplifier is one which does not require linear power
                                                   specifications.

       -WW                                   Specifies Waveguide input and output connectors.

       -NN                                     Specifies N-Type input and output connectors.

       -DI                                      Specifies Drop-In amplifier package.
