Weinschel C O R P O R A T I O N Model 9003, 9004, 9009, 9010, & 9011 Manual Step Attenuators dc to 18.0 GHz 2 Watt Ruggedized SMA Connector Description Features o Broadband - Available in a choice of frequency ranges: dc to 4, dc to 8, dc to 12.4 and dc to 18 GHz. o Wide Choice of Attenuation Ranges - A choice of five standard attenuation ranges is available: 0 to 9.0, 0 to 69 and 0 to 99 dB in 1 dB steps, and 0 to 60 and 0 to 90 dB in 10 dB steps. o Environmental - Designed to meet most environmental requirements of MIL-A-24215 (Vibration, Shock, Relative Humidity to 95% and Altitude). o In-line Configuration - Passivated stainless steel SMA connector are set parallel with control shaft (except units with right angle connector) to reduce volume for applications where space is critical. All models are bidirectional. o Precise Incremental Attenuation Accuracy - Model 9000 series has flat frequency response and small deviation from nominal attenuation at all settings (e.g., deviation is only +2.5 dB at 99 dB setting at 18 GHz). o Excellent Repeatability and Long Switch Life. o Custom Configurations Available Upon Request. o Highly Accurate Detent Stepping - Direct drive of attenuator drums eliminates gears and provides for excellent repeatability. o Safety Mechanical Stop - A mechanical stop between maximum and 0 attenuation positions on all models except 0-9 dB unit is provided to prevent large power changes at attenuator output from damaging sensitive equipment. The Model 9000 series Step Attenuators are broadband miniature step attenuators that provide excellent performance characteristics suitable for use in high reliability 50 ohm systems and applications requiring extra-small components for the precision control of signal levels. The Model 9000 series can be used either as input or output attenuators in signal sources, receivers, field strength meters, spectrum analyzers, etc. The SMA connector furnished on all models are available in either standard or right-angle configuration. The sex of front and rear connector is optional (refer to connector specification for specific combinations available). A knob(s), marked appropriately, is supplied with each unit.
