Description
M/A-COM's AT10-0017 is a PIN diode based voltage
variable attenuator. This device is in a SOIC-16, wide body
plastic surface mount package. These attenuators have
linear operating power and input intercept point levels 15 -
20 dB better than GaAs FET MMIC voltage variable
attenuators. They are ideally suited for use where low
distortion, high linear operating power and high dynamic
range are required. These devices are optimized for the
PCS frequency band, but exhibit excellent performance and
repeatability over the entire specified frequency band. The
AT10-0017 is ideally suited for wireless communications
systems.
Package outline conforms to JEDEC standard MS-013AA.
