BF1108R中文资料数据手册PDF规格书

General description

These switches are a combination of a depletion type Field-Effect Transistor (FET) and a band-switching diode in an SOT143B (BF1108) or SOT143R (BF1108R) package. The low loss and high isolation capabilities of these devices provide excellent RF switching functions. The gate of the MOSFET can be isolated from ground with the diode, resulting in low losses. Integrated diodes between gate and source and between gate and drain protect against excessive input voltage surges.

特性 Features

■ Specially designed for low loss RF switching up to 1 GHz

Applications

■ Various RF switching applications such as:

◆ Passive loop through for VCR tuner

◆ Transceiver switching
