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.
