TEXT
*
The RF2366 is a switchable low noise amplifier with a
very high dynamic range designed for digital cellular
applications. The device functions as an outstanding front
end low noise amplifier. When used as an LNA, the bias
current can be set externally. When used as a PA driver,
the IC can operate directly from a single cell Li-ion battery
and includes a power down feature that can be used to
completely turn off the device. The IC is featured in a
standard SOT 6-lead plastic package.

Amplifier output pin. This pin is an open-collector output. It must be
biased to VCC through a choke or matching inductor. This pin is typically matched to 50Ω with a shunt bias/matching inductor and series
blocking/matching capacitor. Refer to application schematics.
LNA emittance inductance. Total inductance is comprised of
package+bondwire+stripline (L1) on PCB.
This pin selects high gain and bypass.
Select < 0.8V, high gain.
Select > 1.8V, low gain.
