F2258

Voltage Variable RF Attenuator GENERAL DESCRIPTION The F2258 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 50 MHz to 6000 MHz. In addition to providing low insertion loss, the F2258 provides excellent linearity performance over its entire voltage control and attenuation range. The F2258 uses a single positive supply voltage of 3.15 V to 5.25 V. Another feature includes multidirectional operation meaning the RF input can be applied to either RF1 or RF2 pins. Control voltage ranges from 0 V to 3.6 V. COMPETITIVE ADVANTAGE F2258 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: @ 2000 MHz: 1.4 dB vs. 2.8 dB @ 6000 MHz: 2.7 dB vs. 7.0 dB  Maximum Attenuation Slope: 33 dB/Volt vs. 53 dB/Volt  Minimum Return Loss up to 6000 MHz: 12.5 dB vs. 7 dB  Minimum Output IP3: 31 dBm vs. 15 dBm  Minimum Input IP2: 87 dBm vs. 80 dBm  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  Satellite Receivers and Modems  WIMAX Receivers and Transmitters  Military Systems, JTRS radios  RFID handheld and portable reade...
