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 d...
