RFMD unveils broadband 6-bit digital step attenuators

RF Micro Devices Inc of Greensboro, NC, USA has launched its broadband 6-bit digital step attenuator (DSA) product portfolio, with the availability of the RFSA2614 and RFSA2624, to be showcased at the electronica 2010 trade show in Munich Germany (9–12 November).

The firm’s newest high-performance components are optimized for operation across multiple market segments, including 3G/4G/LTE cellular infrastructure, WiMAX, wireless backhaul and other wireless communications applications.

The RFSA2614 and RFSA2624 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 the 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 have a settling time of 200ns, as well as a P1dB (1 dB compression point) of 27dBm and a IIP3 (3rd-order intercept point) of +48dBm.
