Description
The AL107-84 is a high dynamic range amplifier for
1800 MHz applications. The amplifier has high input IP3
of 21 dBm, low noise figure of 2.9 dB and operates from
a single positive bias of +5 V. External resistor sets the
amplifier drain current. No external matching elements are
required. As a low noise driver amplifier it is ideally suited
for 1800 MHz wireless base station applications. The
AL107-84 is encapsulated in SOIC-8 package with slug
for improved heat dissipation and reliability.

of +5 V is fed to pin 8. A 100 pF bypass capacitor
should be placed as close as possible to the lead. The
current can be set 50-80 mA by changing value of the
external resistor connected to pin 6. Typical values for the
resistor (R) are 1224
