Broadband 6-Bit Digital Step Attenuators
Source: RF Micro Devices, Inc.
RFMD offers 6-bit digital step attenuators (DSAs) that feature high linearity over the entire 31.5 dB gain control range with excellent step accuracy in 0.5 dB steps. Parts are available with either a parallel control or a serial control interface that are both 3 V and 5 V compatible. Both DSAs offer Class 1B HBM ESD ratings via on-chip ESD circuitry.

RFMD's RFSA2614 and RFSA2624 digital step attenuators (DSAs) feature a 6-bit design with both serial or parallel mode programming, covering a broad frequency range from 50MHz to 4000MHz. Radio designers can use RFMD's DSAs to adjust the gain of high linearity receive and transmit channels over a 31.5dB range with 0.5dB step resolution. The new DSAs deliver industry-leading performance, highlighted by superior settling time of 200ns, as well as a P1dB (1 dB compression point) of 27dBm and a IIP3 (3rd-order intercept point) of +48dBm.
