IDT Introduces Broadband SPST Absorptive RF Switch Featuring Constant Impedance Technology

IDT » F2910

With an Operating Range of 30 to 8000 MHz, the F2910 is a High Linearity, Low Insertion Loss Switch That Targets a Multitude of Wireless and RF Applications

Integrated Device Technology, Inc. (IDT) introduced a new broadband single-pole, single-throw (SPST) absorptive switch developed for a wide range of wireless and RF applications. With an operating frequency range of 30 to 8000 MHz, the IDT® F2910 is a high-linearity, low-insertion loss 50-ohm switch that delivers exceptional RF performance. The device is ideal for 4G/LTE-Advanced base stations, portable wireless applications, point-to-point, public safety infrastructure, and test equipment.

IDT - F2910

The F2910 features IDT’s industry-first K|Z| constant impedance technology, which maintains near-constant impedance when switching RF ports and improves hot switching ruggedness. The device offers excellent linearity and isolation performance while providing a 50-ohm termination on the output port when in isolation mode. The F2910 uses a single supply voltage and supports 3.3 V or 1.8 V control logic for ease of design.
