The F2914 is a 高 reliability, low insertion loss, 50? SP4T absorptive RF switch designed for a multitude of wireless and 其他 RF 应用s. This device covers a broad 频率范围 from 50MHz to 8000MHz. In addition to providing low insertion loss, the F2914 also delivers excellent linearity and isolation performance while providing a 50? termination to the unused RF ports. The F2914 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 F2914 uses a single positive 电源电压 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.

Design & Development (Boards and Kit)
Evaluation Board for 高 Reliability SP4T Absorptive RF Switch
The F2914EVBI is a fully populated evaluation board which allows the customer to easily evaluate the F2914 RF switch.
“Thru” calibration connectors are conveniently located on the eval board to simplify the calibration process prior to making any RF measurements. Each RF port (RF1, RF2, RF3, and RF4) can be connected to RFC by 申请ing the correct control logic voltage to the V1, V2 and V3 control pins as outlined in the F2914 数据表. The Vssext feature gives the customer the option to supply an external negative voltage to the Vssext header pin to shut down the internal charge pump for low spur operation.
