IM-218A INSTALLATION & OPERATING INSTRUCTIONS Models 150, 151, & 152 Programmable Step Attenuators This documentation may not be reproduced in any form, for any purpose unless authorized in writing by Aeroflex / Weinschel, Inc.. © Aeroflex / Weinschel, Inc. Frederick, Maryland 1996 - 2013 REV. 10-14-2013 IM-218A GENERAL This manual provides general installation instructions and wiring data to be used as an aid in installing a Aeroflex / Weinschel 150 Series Programmable Step Attenuator into any system or application. Also included are specifications and other technical data to help in the installation and operation of the 150 Series Programmable Attenuator. This series of Programmable Step Attenuators represents the widest range of programmable attenuators available. The attenuator design is a result of an extensive development program to ensure that they offer long reliable operation with exceptional accuracy. These attenuators provide programmable adjustments of RF signal levels in very precise steps of 1 dB, 5 dB, 10 dB, or higher if required. Each attenuator consists of a cascaded assembly of switched attenuator cells (Figure 1). This series of Programmable Step Attenuators uses a switching structure that provides rapid switching. Figue 1. Cell Schematic PROGRAMMABILITY: In each programmable step Attenuator, solenoids are used to switch the internal resistor card of each cell into and out of the circuit. With positive voltage applied to the common pin (#6) the state (attenuator card or thru line) of a particular section is determined by connecting it’s attenuator card or thru pin to ground. Once the cell is switched, the solenoid is magnetically latched into position and is able to withstand extreme shock and vibration. Internal circuitry is included to interrupt the coil current after switching is complete. This reduces power dissipation even if power is continuously applied. The switching time for each cell is rated at 20 msec maximum which includes the contact settling time. 2 150 Series Programmable Step Attenuators ENVIRONMENTAL: These Model 150 Programmable Step Attenuators have undergone an extensive environmental qualification program and have been subjected to temperature, shock, vibration, and humidity conditions per MIL-STD-202F. These programmable step attenuators operate within these specifications at an ambient temperature of -20° to +75°C. Operating beyond these limits will adversely affect the accuracy and could damage the internal circuitry.

CELL CONFIGURATION The table below list all the standard attenuation ranges and cell configurations for Weinschel 150T Series Smartstep Programmable Attenuators (Models 150, 151, 152). Note the dash number is the attenuation value of your attenuator. Table 1.

These screws will fit any of the mounting holes (4-40 UNC-2B x 0.22 MIN DP) located on either side of the attenuator. RF CABLE INSTALLATION: Care should be taken to prevent strain on the interconnecting cables, since damage here may not always be apparent. Check the attaching RF cables and the 3.5mm connectors for signs of cracked insulation and/or bent or worn pins prior to connection. Tests show that connectors must be clean for accuracy and stability. This requires an inspection and cleaning of each connector immediately before use. When cleaning precautions are observed regularly, connectors can maintain their stability for over several thousand connection cycles. Weinschel recommends a torque value of 7 to 10 inch pounds when connecting any RF cable to the attenuator's RF connectors. CONTROL CONNECTOR WIRING: Table 2 provides the necessary wiring data to connect the attenuator to the appropriate driver circuitry. This table covers both types of attenuator cables. Figure 2 is also provided to show the location of eachcontrol connector pin. Table 2.
