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 multi-
directional 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
