ADRF5703BCCZN

ADRF5703BCCZN is a 7-bit digital attenuator with a 31.75dB attenuation range and 0.25dB step size manufactured in a SOI process. This device operates from 9kHz to 20GHz with an insertion loss better than 1.7dB and excellent attenuation accuracy. The ADRF5703 has RF input power handling capabilities of 27dBm average and 30dBm peak for all states from the ATTIN pin. The ADRF5703 operates with a dual-supply voltage +3.3V and −3.3V. The device can also operate with a single-supply voltage applied while the negative supply voltage is tied to ground. In this operating condition, the small signal performance is maintained while the switching characteristics, linearity, and power handling performance are derated. The device features serial or parallel mode control and CMOS-/low voltage transistor to transistor logic-compatible controls. Typical applications include industrial scanners, test and instrumentation, 5G millimetre wave, military radios, radars, ECMs and microwave radios and VSATs.
