Description
The AM42-0039 is a three stage MMIC power amplifier in a lead -free, bolt down ceramic package, allowing easy assembly. This device employs a fully matched chip with internally decoupled gate and drain bias networks. The device is designed to operate from a constant current drain supply or a constant voltage gate supply. By varying the bias conditions, the saturated output power performance of this device may be tailored for various applications. The AM42-0039 is ideally suited for use as an output stage or a driver amplifier in VSAT systems. The AM42-0039 includes internal supply line bypassing in the package, minimizing the number of external components required. The AM42-0039 is fabricated using a mature 0.5 micron MBE based GaAs MESFET process. The process features full passivation for increased performance and reliability. This product is 100% RF tested to ensure compliance to performance specifications. Part Number Package AM42-0039 CR-15 Ceramic Bolt Down Package Pin Configuration Pin No. Pin Name Description

V — 4.0 — Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. Operating the AM42-0039 The AM42 -0039 is static sensitive. Please handle with care. To operate the device, follow these steps. 1. Apply -2.0 Volts to VGG. 2. Ramp VDD to +8V. 3. Adjust VGG to set quiescent drain current . 4. Apply RF. 5. Power down in reverse sequence. Turn gate voltage off last.

Exceeding any one or combination of these limits may cause permanent damage to this device. 2. M/A-COM does not recommend sustained operation near these survivability limits. 3. Adequate heat sinking and grounding required on flange base.
