RF Micro Devices announced the launch of its broadband 6-bit digital step attenuator product portfolio with the availability of the RFSA2614 and the RFSA2624.
The components are optimised for operation across multiple market segments, including 3G/4G/LTE cellular infrastructure, WiMAX, wireless backhaul and other high-performance wireless communications.
The digital step attenuators (DSAs) feature a 6-bit design with both serial or parallel mode programming, covering a broad frequency range from 50 MHz to 4000 MHz. Radio designers can use them to adjust the gain of high-linearity receive and transmit channels over a 31,5 dB range with 0,5 dB step resolution. The devices deliver settling time of 200 ns and a P1dB (1 dB compression point) of 27 dBm and IIP3 (3rd-order intercept point) of +48 dBm.
