IDTF2255 Datasheet | Renesas

Voltage Variable RF Attenuator 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. PETITIVE ADVANTAGE IDTF2255 provides extremely low insertion loss and superb IP3, IP2, Return Loss and Slope Linearity across the control range. paring to petitive VVAs this device is better as follows: - Operation down to 1MHz - Insertion Loss @ 500MHz: 1.1d B - Maximum Attenuation Slope: 33d B/Volt - Minimum Output IP3: 35d Bm - Minimum Input IP2: 74d Bm - 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 IDTF2255NLGK 1MHz to 3000MHz Features - Low Insertion Loss: 1.1d B @...
