1 VDI USER GUIDE Product: 1900 GHz Amplifier Multiplier Chain Serial Number(s): VDI-AMC-S186B (upgrade) Amplifier: Spacek Labs A286-2XWB-33 SN 8M18 Components: VDI 52R1X2 1-17, VDI 110R1X2 1-14, VDI 200R2X2 1-03, VDI WR0.51X (upgrade) Horn: Integrated WR0.51 horn antenna VDI Power Box; VDI Bias and Control Box Virginia Diodes Inc., (434) comp151-Uaz-1.9THz AMC-1 (original) 5/4/ Uaz-THz AMC upgrades- 2 (upgrade) 04/14/10 JD Section 1 User Guide Overview The customer must read the entire User Guide prior to handling, testing, biasing, or using this product. This document gives a general description of the product, several important warnings to be considered when using the product, and basic operating instructions. This VDI product includes a 1900 GHz amplifier multiplier chain system, designed for full-power operation upon initial turn-on. The AMC was returned to VDI for upgrade. The WR1.5X3R2 and WR0.5X3 were replaced with a WR0.51X9 to improve the output power of the AMC. Warning - Read the entire VDI User guide for this product prior to operation. Warning - This product can be permanently damaged by ElectroStatic Discharge (ESD). It is recommended that engineers and technicians wear a special grounded wrist strap when handling this component. In addition, the work environment around the component should be well grounded. Warning Opening the blocks, parts, or components will damage the internal components. VDI is not responsible for the warranty or guaranty of products damaged as a result of improper handling, testing, biasing, or use by customer. Caution - VDI assumes the customer is familiar with microwave, millimeter wave, and VDI products. The user and customer are expected to understand all safety guidelines, health hazards, and general advisories that may exist and are associated with the use of this device. VDI is not responsible for any human hazards that may exist or may occur while using this device.

Section 2 General Operating Procedures and Guidelines VDI assumes the customer is familiar with VDI products, and VDI is not responsible for the warranty or guaranty of products damaged as a result of improper handling, testing, biasing, or use by customer. VDI offers the following general guidelines for using these products and recommends the customer contact VDI at (434) for assistance if needed. The following procedures are a quick guide for turning on and off the product. In each case the individual steps must be followed in the proper sequence to avoid damaging critical components. Warning - RF drive limitations, voltage bias limitations, and current limitations may exist for this device and are described below. Exceeding these limitations and guidelines may cause permanent damage to the device. The drive and bias guidelines, limitations, and recommendations for this product are: RF input power must be less than 20dBm for safe operation; 17-18dBm for saturated RF output power. Do not tamper with the SMA or other connections. Remove the waveguide tape on the output horn of the AMC prior to initial use. Do not add attenuation to the bias ports of the multipliers. This will change the voltage biasing and damage the multipliers when RF power is turned on. Contact VDI with questions or concerns regarding the product RF drive limitations, voltage bias limitations, and current limitations. The following procedure is to be used when turning on the device. Step A: The user and test bench must be properly grounded and protected against ESD. Step B: Connect the system to the VDI Power Box and turn it on. Step C: Slowly turn up RF input power (17-18dBm expected for saturation; do not exceed 20dBm). After completing these steps the system is ready for full-power operation.

5 Step D: If desired, the user can modulate (<1kHz) the output power of the source by applying a 0-5 volt signal to the TTL Modulation BNC Input. 0VDC causes full power out and 5VDC causes no power out. Step E: If desired, the user can attenuate the output power of the source by applying a 0-5VDC to the Voltage Controlled Attenuation BNC Port. 0VDC causes no attenuation and 5VDC causes full attenuation. The following procedure is to be used when turning off the device. Step A: The user and test bench must be properly grounded and protected against ESD. Step B: Turn off RF input power. Step C: Turn off the Power Box. Step D: After completing turn-off procedures described above, it is now safe to turn off any other equipment on the Test Bench.
