The F2910 is a rugged, low insertion loss, 50 Ω SPST absorptive RF switch designed for a multitude of wireless and other RF applications.  This device covers a broad frequency range from 30 MHz to 8000 MHz.  In addition to providing low insertion loss, the F2910 also delivers excellent linearity and isolation performance while providing a 50 Ω termination to the RF2 port when isolated.  This product also incorporates IDT’s new Constant Impedance, Kz, feature. The Kz feature maintains a near constant impedance when switching between RF ports preserving a higher RF port return loss. Standard switches without Kz create a large Voltage Standing Wave Ration (VSWR) transient when switching RF paths because the impedance of the switch in not well controlled during the switching event due to poor RF port return loss. These VSWR transients can potentially reduce the ruggedness of the switch itself and can also subject downstream components to large voltage stresses reducing ruggedness and degrading overall system performance. IDT’s Kz feature controls the impedance during the switching process minimizing the VSWR transient thereby improving switch ruggedness, reducing voltage stresses on downstream components and improving overall system performance.
