Philips Semiconductors Product specification

N-channel single gate MOS-FETs BF1107; BF1107W

FEATURES

• Currentless RF switch.

APPLICATIONS

• Various RF switching applications such as:

- Passive loop through for VCR tuner

- Transceiver switching.

DESCRIPTION

The BF1107 and BF1107W are depletion type field-effect
transistors in SOT23 and SOT323 packages respectively.
The low loss and high isolation capabilities of this
MOS-FET provide excellent RF switching functions.
Integrated diodes between gate and source and between
gate and drain protect against excessive input voltage
surges. Drain and source are interchangeable.
