50 MHz to 4000 MHz Digital Step AttenuatorsSource: RFMD
These digital step attenuators operate in the 50 MHz to 4000 MHz frequency range and are ideal for applications involving test equipment, transceiver RF/IF, 2G, 3G, LTE, WiMax/WiFi, wireless data, and satellite terminals. They feature 1.2 dB insertion loss at 2 GHz, high linearity (IIP3 >48 dBm for all steps), 3V and 5V logic compatibility, a serial programming interface, and more.
At 15.5 dB, the RFSA2514 Digital Step Attenuator has a 0.5dB step. At 31dB, the RFSA2524 has a 1 dB step. Additional information can be found on the available datasheets.
