F2250NLGK8

Voltage Variable RF Attenuator GENERAL DESCRIPTION The F2250 is a low insertion loss Voltage Variable RF Attenuator (VVA) designed for a multitude of wireless and other RF applications. This device covers a broad frequency range from 50MHz to 6000MHz. In addition to providing low insertion loss, the F2250 provides excellent linearity performance over its entire voltage control and attenuation range. The F2250 uses a single positive supply voltage of 3.15V to 5.25V. Other features include the VMODE pin allowing either positive or negative voltage control slope vs attenuation and multi-directional operation meaning the RF input can be applied to either RF1 or RF2 pins. Control voltage ranges from 0V to 3.6V using either positive or negative control voltage slope. COMPETITIVE ADVANTAGE F2250 provides extremely low insertion loss and superb IP3, IP2, Return Loss and Slope Linearity across the control range. Comparing to the previous state-of-theart for silicon VVAs this device is better as follows:  Insertion Loss @ 2000MHz: 1.4dB vs. 2.8dB  Insertion Loss @ 6000MHz: 2.7dB vs. 7dB  Maximum Attenuation Slope: 33dB/Volt vs. 53dB/Volt  Minimum Return Loss up to 6000MHz: 12.5dB vs. 7dB  Minimum Output IP3: 31dBm vs. 15dBm  Minimum Input IP2: 87dBm vs. 80dBm  Maximum Operating Temperature: +105°C vs. +85°C APPLICATIONS  Base Station 2G, 3G, 4G  Portable Wireless  Repeaters and E911 systems  Digital Pre-Distortion  Point to Point Infrastructure  Public Safety Infrastructur...
