F2971 Datasheet | IDT

Description The F2971 is a high reliability, low insertion loss, 75Ω absorptive SP2T RF switch designed for a multitude of cable systems and RF applications. This device covers a broad frequency range from 5MHz to 3000MHz. In addition to providing low insertion loss, the F2971 also delivers excellent linearity and isolation performance while providing a 75Ω termination for the unselected port. The F2971 uses a single positive supply voltage and supports 3.3V logic. petitive Advantage The F2971 provides broadband RF performance to support the CATV market along with high power handling and high isolation. - Low insertion loss - High isolation - Excellent linearity - Extended temperature: -40°C to +105°C Typical Applications - CATV/Broadband applications - Headend - Fiber/HFC distribution nodes - Distribution amplifiers - Switch matrix - DTV tuner input select - DVR/PVR/Set-top box - CATV test equipment Features - Low insertion loss: 0.31d B at 1200MHz - High Isolation: 71d B at 1200MHz (RF1/RF2 to RFC) - High IIP3: 67d Bm at 5MHz - Operating Temperature: -40°C to +105°C - 4mm x 4mm, 20-pin LQFN package Block Diagram Figure 1.
