Function
VCC1
Description
Supply voltage for the LNA. External RF and IF bypassing is required.
The trace length between the pin and the bypass capacitors should be
minimized. The ground side of the bypass capacitors should connect
immediately to ground plane. This pin connects to pin 8 through a
150
resistor. This allows for simple biasing of the collector at pin 6.
Refer to Application Schematics 1 and 3.
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
RF input pin. This pin is internally DC-blocked and matched to 50
for
frequencies above 1GHz. When using below 1GHz, it is recommended
that this pin be matched with series inductance to series-resonate out
the internal blocking capacitor. Refer to Application Schematics 1 and
2.

LNA Output pin. This pin is an open-collector output. It must be biased
to either V
CC
or pin 8 through a choke or matching inductor. This pin is
typically matched to 50
with a shunt bias/matching inductor and
series blocking/matching capacitor. Refer to application schematics.
No connection. This pin is typically left unconnected or grounded.
See pin 3.

Optional power supply connection for biasing pin 6. This pin connects
to pin 1 through a 150
resistor. This allows for simple biasing of the
collector at pin 6. When used, this pin should be RF bypassed. Refer to
Application Schematics 1 and 3.
