RF Micro Devices Inc., a global leader in the design and manufacture of high-performance radio frequency components and compound semiconductor technologies, 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 single-pole, double-throw switch (SPDT).

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 other data network equipment.

Cable industry designers using RFMD's new digital step attenuator can adjust the gain of high linearity amplifier lineups over a 31.5 dB range with 0.5 dB step resolution. The RFSA2654 also delivers ultra-fast switching speeds, solving 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.

RFMD is showcasing their new control components at the SCTE Cable-TEC Expo in Orlando, Florida, October 17-19, in booth 2324. Samples and production quantities are available now through RFMD's online store or through local RFMD sales channels. To request a datasheet, go to www.rfmd.com or contact RFMD at 336-664-1233.
