IDT Introduces Family of SPDT Reflective RF Switches with Wide Frequency Range, Low Distortion, and Low Insertion Loss

IDT » F2972, F2976

Supporting a Frequency Range of 5MHz to 10GHz, the New Devices Deliver Superior RF Performance in Tiny 2 mm × 2 mm Packages

Integrated Device Technology (IDT) introduced a new family of high-performance single-pole, double throw reflective (SPDTR) RF switches in compact 2 mm × 2 mm packages. The F2972 and F2976 operate from 5 MHz to 10 GHz, offering an industry-leading mix of low-insertion loss, high isolation, low distortion and high power handling.

IDT - F2972, F2976

The IDT® devices are specified for use in either 50 or 75 ohm systems, offering versatility for a wide range of markets and applications, including, BTS wireless communications equipment, DOCSIS 3.1 CATV applications, drones, and general purpose consumer products.

The F2972 and F2976 have similar RF performance and pin outs, however each device has a unique feature pin. The F2972 offers an enable/disable pin for green, low-power consumption applications. The F2976 has a logic-select feature pin that allows the user to invert the switch control logic, enabling the control of multiple switches with a single control line where each switch needs to be in different states.
