1 / 24 page  Voltage Variable RF Attenuator 50MHz to 6000MHz Voltage Variable RF Attenuator 1 REV 4, January 2017 F2250NLGK Datasheet 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-the- art 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 Infrastructure WIMAX Receivers and Transmitters Military Systems, JTRS radios RFID handheld and portable readers Cable Infrastructure Wireless LAN Test / ATE Equipment FEATURES Low Insertion Loss: 1.4dB @ 2000MHz Typical / Min IIP3: 65dBm / 47dBm Typical / Min IIP2: 95dBm / 87dBm 33.6dB Attenuation Range Bi-directional RF ports +34.4dBm Input P1dB compression VMODE pin allows either positive or negative attenuation control response Linear-in-dB attenuation characteristic Supply voltage: 3.15V to 5.25V VCTRL range: 0V to 3.6V using 5V supply +105°C max operating temperature 3mm x 3mm, 16-pin QFN package DEVICE BLOCK DIAGRAM ORDERING INFORMATION PART# MATRIX Part# RF Freq Range (MHz) Insertion Loss (dB) IIP3 (dBm) Pinout Compatibility F2250 50 - 6000 1.4 (at 2GHz) +65 RFMD F2255 1 - 3000 1.1 (at 500MHz) +60 F2258 50 - 6000 1.4 (at 2GHz) +65 Hittite RF1 RF2 Control F2250NLGK8 0.9 mm height package Green Temp Range Tape & Reel RF Product Line |
