RFMD introduces new control components for cable application


Broadband digital step attenuator and high power double throw switch

RFMD new CATV control components

RF Micro Devices, Inc designer and manufacturer of high-performance RF (radio frequency) components and compound semiconductor technologies, has unveiled two new CATV control components, in conjunction with the SCTE Cable-TEC Expo, in Orlando, FL. The new components include the RFSA2654, a 75-ohm broadband digital step attenuator, and the RFSW1012, a high power handling SPDT (single-pole, double-throw switch). RFMD's RFSA2654 is a 6-bit serial controlled digital step attenuator with high linearity operating over a 5MHz to 2000MHz frequency range. RFMD's RFSW1012 is a 3-volt silicon on insulator (SOI) switch operating over a 5MHz to 6000MHz range combining low insertion loss, high isolation, and high linearity. The state-of-the art new devices are ideally suited for cable modems, CATV infrastructure, and data network equipment. Cable industry designers using RFMD's new digital step attenuator can adjust the gain of high linearity amplifier lineups over a 31.5dB range with 0.5dB step resolution. The RFSA2654 also delivers ultra-fast switching speeds, overoming a common problem facing step attenuators in many CATV applications. RFMD's RFSW1012 delivers 0.3 dB insertion loss, 48 dB isolation, and CTB/CSO > 100 dBc measured at +41 dBmV/channel for 137 channels. The new SPDT also features a robust 2kV human body model (class 2) ESD rating on all ports and is housed in a reduced-size 2mm x 2mm 12-pin QFN package. Samples and production quantities are available now through RFMD's online store or through local RFMD sales channels. RFMD
