Description

M/A-COM's AT10-0019 is a Voltage Controlled PIN diode
based π attenuator packaged in a low cost, 16 lead wide
body plastic SMT package. The PIN diode design makes
this part well suited for applications where low distortion or
high linear operating power levels are required. These
attenuators are ideal for gain control in multi-channel
digital communications systems.
