RFMD introduces new CATV control components

RF Micro Devices Inc (RFMD) of Greensboro, NC, USA, a manufacturer of radio frequency components and compound semiconductor technologies, has introduced two new CATV control components at this week’s SCTE Cable-TEC Expo in Orlando, FL, USA.

RFSA2654 is a 75-ohm broadband, 6-bit serial controlled digital step attenuator, with high linearity operating over a 5MHz to 2000MHz frequency range. 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, says the firm.

RFSW1012 is a high power handling single-pole, 3-volt silicon on insulator (SOI) double-throw switch (SPDT), operating over a 5MHz to 6000MHz range. It 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 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.

Both devices are suited for cable modems, CATV infrastructure, and other data network equipment.

Samples and production quantities are available now.
