Description
M/A-COM's AT10-0009 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 GSM
frequency band, but exhibit excellent performance
and repeatability over the entire specified frequency
band. The AT10-0009 is ideally suited for wireless
communications systems.
