特性
The ADRF5714 is a silicon, 1-bit digital attenuator with 16 dBattenuation supporting glitch-free operation.
This device operates from 100 MHz to 30 GHz with better than 1.3dB of insertion loss and excellent attenuation accuracy. The ATTINport of the ADRF5714 has an RF input power handling capability of30 dBm average and 33 dBm peak.
The ADRF5714 requires a dual-supply voltage of +3.3 V and −3.3V. The device features complementary metal-oxide semiconductor(CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatiblecontrol.
The ADRF5714 can also operate with a single positive supplyvoltage (VDD) applied. The negative supply voltage (VSS) is tied toground. See the Theory of Operation section in the data sheet for more details.
The ADRF5714 RF ports are designed to match a characteristicimpedance of 50 Ω. The ADRF5714 comes in a 12-terminal, 2.25mm × 2.25 mm, RoHS compliant, LGA package and operates from−40°C to +105°C.
