F2915

The F2915 is a 高 reliability, low insertion loss, 50Ω SP5T absorptive RF switch designed for a wide 范围 of wireless and 其他 RF 应用s. This device covers a broad frequency 范围 from 50MHz to 8000MHz. In addition to providing low insertion loss, the F2915 also delivers excellent linearity and isolation performance while providing a 50Ω termination to the unused RF ports. The F2915 also includes a patent-pending constant impedance (Kz) feature. Kz improves hot switching ruggedness, minimizes LO pulling in VCOs, and reduces phase and amplitude variations in distribution networks. It is also ideal for dynamic switching/选择ion between two or more amplifiers while avoiding damage to upstream/downstream sensitive devices such as PAs and ADCs.

The F2915 uses a single positive supply voltage 支持ing three logic control pins using either 3.3V or 1.8V control logic. Connecting a negative voltage to pin 20 disables the internal negative voltage generator and becomes the negative supply.
