BF1102R General Description
The BF1102 and BF1102R are both two equal dual gate MOS-FETs which have a shared source pin and a shared gate 2 pin. Both devices have interconnected source and substrate; an internal bias circuit enables DC stabilization and a very good cross-modulation performance at 5 V supply voltage; integrated diodes between the gates and source protect against excessive input voltage surges. Both devices have a SOT363 micro-miniature plastic package.
