Silicon Digital Attenuator, 1-Bit, 1 MHz to 30 GHz

The ADRF5715 is a silicon, 1-bit digital attenuator with 16 dB attenuation.

The ADRF5715 operates from 1 MHz to 30 GHz with better than 1.15 dB of insertion loss and excellent attenuation accuracy. The ATTIN and ATTOUT port of the ADRF5715 have an RF power handling capability of 30 dBm steady state average and 33 dBm steady state peak.

The ADRF5715 requires a dual-supply voltage of +3.3 V and −3.3 V. The device features complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls.

The ADRF5715 can also operate with a single positive supply voltage (VDD) applied while the negative supply voltage (VSS) is tied to ground. See the Theory of Operation section for more details.

The ADRF5715 RF ports are designed to match a characteristic impedance of 50 Ω. The ADRF5715 comes in a 12-terminal, 2.25 mm × 2.25 mm, RoHS-compliant, LGA package and operates from −40°C to +105°C.
