F2250NLGK Datasheet, PDF (1/24 Pages) Integrated Device Technology – Voltage Variable RF Attenuator

Voltage Variable RF Attenuator
GENERAL DESCRIPTION
The F2250 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 50MHz to 6000MHz. In addition
to providing low insertion loss, the F2250 provides
excellent linearity performance over its entire voltage
control and attenuation range.
The F2250 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.
COMPETITIVE ADVANTAGE
F2250 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 @ 2000MHz: 1.4dB vs. 2.8dB
 Insertion Loss @ 6000MHz: 2.7dB vs. 7dB
 Maximum Attenuation Slope: 33dB/Volt vs. 53dB/Volt
 Minimum Return Loss up to 6000MHz: 12.5dB vs. 7dB
 Minimum Output IP3: 31dBm vs. 15dBm
 Minimum Input IP2: 87dBm vs. 80dBm
 Maximum Operating Temperature: +105°C vs. +85°C
