Description
M/A-COM's AT10-0019 is a Voltage Controlled PIN
diode based p 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.
