BF1218 Overview
The BF1218 is a bination of two dual gate MOSFET amplifiers with shared source and gate2 leads and an integrated switch. The integrated switch is operated by the gate1 bias of amplifier B. The source and substrate are interconnected.
BF1218 Key Features
- Two low noise gain controlled amplifiers in a single package. One with a fully integrated bias and one with a partly int
