General Description
The CFA0103-L series is a family of low noise, high-gain FETs intended for satellite and point-to-point radio receiver
applications. This family of devices is assembled in an industry standard 70 mil hermetic package. This family of high
reliability devices is ideally suited for operation-critical applications where reliability and performance are required.
