Voltage Variable RF Attenuator F2251 50MHz to 6000MHz Datasheet Description Features The F2251 is a low insertion loss Voltage Variable RF Attenuator Frequency range: 50MHz to 6000MHz (VVA) designed for a multitude of wireless and RF applications. Low insertion loss: 1.4dB at 2000MHz The device covers a broad frequency range from 50MHz to Typical/Minimum IIP3: 67dBm / 47dBm 6000MHz. In addition to providing low insertion loss, the F2251 Typical/Minimum IIP2: 105dBm / 95dBm provides excellent linearity performance over its entire voltage 33.6dB attenuation range control and attenuation range. Bi-directional RF ports The F2251 uses a single positive supply voltage of 3.15V to 5.25V. Other features include an enhancement to the Phase Noise +34.4dBm Input P1dB compression performance of the device compared to its predecessor (F2250). Enhanced phase noise performance The device also features a positive attenuation slope only. Linear-in-dB attenuation characteristic Supply voltage: 3.15V to 5.25V Competitive Advantage V range: 0V to 3.6V using 5V supply CTRL +105C maximum operating temperature The F2251 provides extremely low insertion loss and superb IP3, IP2, Return Loss, and Slope Linearity across the control range. 3 3 mm 16-VFQFPN package Comparing to the previous state-of-the-art for silicon VVAs, this device provides superior performance: Block Diagram Insertion loss at 2000MHz: 1.4dB Insertion loss at 6000MHz: 2.6dB Figure 1.
