Device Overview

General Description

The AMM-7200ACH is a general-purpose broadband MMIC driver amplifier that provides +20 dBm output power suitable for driving a Marki H or L diode mixer at 12-46 GHz and S diode mixer from 14-40 GHz with low current consumption. The amplifier also has excellent return losses and a small die size which allows it to be used in a variety of applications. It has built in DC-blocking capacitors on the input and output.

The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings. Power Supply DC current should be modified by changing bias voltage Vg to maintain junction temperature within MTTF target for given operating conditions.
