F2251

Voltage Variable RF Attenuator 50MHz to 6000MHz F2251 Datasheet Description The F2251 is a low insertion loss Voltage Variable RF Attenuator (VVA) designed for a multitude of wireless and RF applications. The device covers a broad frequency range from 50MHz to 6000MHz. In addition to providing low insertion loss, the F2251 provides excellent linearity performance over its entire voltage control and attenuation range. The F2251 uses a single positive supply voltage of 3.15V to 5.25V. Other features include an enhancement to the Phase Noise performance of the device compared to its predecessor (F2250). The device also features a positive attenuation slope only. Competitive Advantage The F2251 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 provides superior performance:  Insertion loss at 2000MHz: 1.4dB  Insertion loss at 6000MHz: 2.6dB  Maximum attenuation slope: 29dB/Volt  Minimum return loss up to 6000MHz: 14dB  Minimum output IP3 at maximum attenuation: 34dBm  Minimum input IP2: 95dBm  Maximum operating temperature: +105°C Typical 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 infrastruct...
