特性
The ADRF5716 is a silicon, 2-bit digital attenuator with 48 dBattenuation control range in 16 dB steps supporting glitch-freeoperation.
This device operates from 100 MHz to 30 GHz with better than 2.9dB of insertion loss and better than 1.5 dB attenuation accuracy.The ATTIN port of the ADRF5716 has a RF input power handlingcapability of 30 dBm average and 33 dBm peak for all states.
The ADRF5716 requires a dual-supply voltage of +3.3 V and −3.3V. The device features parallel mode control, and complementarymetal-oxide semiconductor (CMOS)-/low voltage transistor to transistorlogic (LVTTL)-compatible controls.
The ADRF5716 can also operate with a single positive supplyvoltage (VDD) applied, and the negative supply voltage (VSS) is tiedto ground. See the Theory of Operation section in the data sheet for more details.
The ADRF5716 RF ports are designed to match a characteristicimpedance of 50 Ω. The ADRF5716 comes in a 20-terminal, 3mm × 3 mm, RoHS compliant, land grid array [LGA] package andoperates from −40°C to +105°C.
