F2912 Datasheet, PDF (1/23 Pages) Integrated Device Technology – High Reliability SP2T RF Switch

High Reliability SP2T RF Switch
GENERAL DESCRIPTION
The F2912 is a high reliability, low insertion loss, 50 Ω
SP2T absorptive RF switch designed for a multitude of
wireless and other RF applications. This device covers
a broad frequency range from 9 kHz to 9000 MHz. In
addition to providing low insertion loss, the F2912 also
delivers excellent linearity and isolation performance
while providing a 50  termination to the unused RF
input port.
The F2912 uses a single positive supply voltage of
3.3 V supporting three states using either 3.3 V or
1.8 V user-selectable control voltage. An added
feature includes a Mode CTL pin allowing the user to
control the device with either 1-pin or 2-pin control.
COMPETITIVE ADVANTAGE
The F2912 provides extremely low insertion loss;
particularly important for RF receiver front-end use.
 Insertion Loss : 0.4 dB @ 1 GHz
 IIP3: +66 dBm
 RF1 to RF2 Isolation: 74 dB@ 1 GHz
 Negative supply voltage not required
 Extended temperature -55 °C to +125 °C
