1 / 24 page  Voltage Variable RF Attenuator 1MHz to 3000MHz Voltage Variable RF Attenuator 1 REV O, July 2015 IDTF2255NLGK Datasheet GENERAL DESCRIPTION The IDTF2255 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 1MHz to 3000MHz. In addition to providing low insertion loss, the IDTF2255 provides excellent linearity performance over its entire voltage control and attenuation range. The F2255 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 IDTF2255 provides extremely low insertion loss and superb IP3, IP2, Return Loss and Slope Linearity across the control range. Comparing to competitive VVAs this device is better as follows: Operation down to 1MHz Insertion Loss @ 500MHz: 1.1dB Maximum Attenuation Slope: 33dB/Volt Minimum Output IP3: 35dBm Minimum Input IP2: 74dBm High Operating Temperature: +105°C APPLICATIONS • Base Station 2G, 3G, 4G, • Portable Wireless • Repeaters and E911 systems • Digital Pre-Distortion • Point to Point Infrastructure • Public Safety Infrastructure • Satellite Receivers and Modems • WIMAX Receivers and Transmitters • Military Radios covering HF, VHF, UHF • RFID handheld and portable readers • Cable Infrastructure • Wireless LAN • Test / ATE Equipment FEATURES • Low Insertion Loss: 1.1dB @ 500MHz • Typical / Min IIP3: 60dBm / 46dBm • Typical / Min IIP2: 98dBm / 74dBm • 33dB Attenuation Range • Bi-directional RF ports • +36dBm Input P1dB compression • VMODE pin allows either positive or negative 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 • 3x3, 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 IDTF2255NLGK8 0.9 mm height package Green Tape & Reel Omit IDT prefix RF product Line |
