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.
The F2910 features IDT’s industry-first Kz 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.
“The F2910 is the latest example of IDT’s commitment to serving the RF community through innovative, high-performance devices,” said Duncan Pilgrim, general manager of IDT’s RF Division. “By featuring our unique Kz technology in a broadband SPST absorptive switch, IDT is able to offer a device that meets or exceeds the needs engineers have for wide variety of RF applications.”
