Description
M/A-COM's AM42-0002 is a three-stage MMIC linear power amplifier in a lead-free, ceramic bolt down style hermetic package. The AM42-0002 employs a fully matched chip with internally decoupled gate and drain bias networks and an output power detector. The AM42-0002 is designed to be operated from a constant voltage drain supply. The AM42-0002 is designed for use as an output stage or a driver, in applications for VSAT systems. This design is fully monolithic and requires a minimum of external components. M/A-COM's AM42-0002 is fabricated using a mature 0.5 micron 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.

1. 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. Case Temperature (TC) = +25C.
Handling Procedures
Please observe the following precautions to avoid damage:
4. Nominal bias is obtained by first connecting -5 volts to pin 4 (VGG), followed by connection +9 volts to pin 6 (VDD). Note sequence. 5. RF ground and thermal interface is the flange (case bottom). Adequate heat sinking is required. 6. No DC bias voltage appears at the RF ports. 7. The DC resistance at the input port is an open circuit and at the output port is a short circuit. 8. For optimum IP3 performance, the VDD bypass capacitors should be placed within 0.5 inches of pin 6. 9. Resistor and capacitors surrounding the amplifier are suggestions and not included as part of the AM42-0002.
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.
