 CBMG719 Product Highlights


● The CBMG719 switch features low power consumption, fast switching speed, low on-resistance, and small leakage current.

       ● Each switch within the CBMG719 exhibits identical conduction performance in both directions when turned on. The CBMG719 is of the break-before-make type. Additionally, the device can achieve a −3 dB bandwidth greater than 200 MHz.

       ● The chip functions normally across a temperature range from -40°C to +125°C, demonstrating a certain level of reliability.
