Description
M/A-COM's MAAVCC0001 is a PIN diode based voltage
variable attenuator. This device is in a 6mm square, 28 lead,
plastic CSP Package, suitable for surface mounting on
PCBs. 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 MAAVCC0001 is ideally
suited for wireless communications systems.
Package outline conforms to JEDEC standard MO-220B.
