Variable Gain Control, X Band Connectorised Amplifier: 8 – 12 GHz MAAMML0018 V4 Features • • • • • • • High Reliability Weight and space saving design Field Replaceable SMA Connectors Monotonic Gain Control >= 28dB Gain control < 4.5us settled gain switching time. Space Qualified version available Description The MAAMML0018 is a high reliability X band variable gain amplifier. This weight and space saving design has been realised by utilising the latest advances in housing materials. A variable attenuator is followed by an X band amplifier. This allows total unit gain to be adjustable over a >= 28dB range, from an applied control voltage. Alternative frequency ranges, gain, output powers and supply rail configurations are available. The MAAMML0018 is also available as a space qualified version. Please contact the factory for details. Mechanical This device is supplied with field replaceable SMA connectors. It is hermetically sealed, with a gold-plated finish to MIL-G-45204.
