KGA4217L
Limiting Amplifier IC
Preliminary
DESCRIPTION
KGA4217L, limiting Amplifier IC with 0.18
µm
gate length GaAs MESFETs, has been designed for 10 Gb/s
digital communication systems. By using DCFL(Direct Coupled FET Logic), high speed operation of 10 Gb/s
and low power dissipation have been realized. Capacitive coupling is recommended for I/O connections.
