Analog Devices have introduced the ADRF5740 4-bit digital attenuator manufactured using a silicon process that is designed to operate across an ultrawideband frequency range of 10 MHz to 60 GHz with low insertion loss. The device features high input linearity and allows attenuation control in 2 dB steps up to 22 dB, with attenuation accuracy of ±(0.1 + 1.0% of state) up to 20GHz and ±(0.2 + 7.0% of state) up to 55GHz with a typical step error of just ±0.30 dB and ±0.60 dB respectively.
The ADRF5740 has an RF input (ATTIN) power handling capability of 24 dBm average and 24 dBm peak for all states and operates from a dual supply voltage of ±3.3 V. The ADRF5740 RF ports are designed to match a characteristic impedance of 50 Ω. The device has a flexible control interface supporting parallel mode control, and CMOS- and low voltage transistor to transistor logic (LVTTL)-compatible controls.
