RFMD introduces new control components for cable applications

RF Micro Devices has unveiled two new CATV control components: the RFSA2654, a 75ohm broadband digital step attenuator and the RFSW1012, a high power handling single pole, double throw switch (SPDT).

The RFSA2654 is a 6bit serial controlled digital step attenuator with high linearity operating over a 5 to 2000MHz frequency range. The RFSW1012 is a 3V silicon on insulator (SOI) switch operating over a 5 to 6000MHz range combining low insertion loss, high isolation, and high linearity.

The new devices are said to be suitable for cable modems, CATV infrastructure and other data network equipment. Cable industry designers using the new digital step attenuator can adjust the gain of high linearity amplifier lineups over a 31.5dB range with 0.5dB step resolution.

RFMD's RFSW1012 is designed to deliver 0.3dB insertion loss, 48dB isolation and CTB/CSO > 100dBc measured at 41dBmV/channel for 137 channels. The new SPDT also features a 2kV human body model (class 2) ESD rating on all ports and is housed in a 2mm x 2mm 12pin QFN package.
