900 MHz GaAs
LOW NOISE AMPLIFIER
WITH GAIN CONTROL
Designed primarily for use in 900 MHz wireless communication systems
such as GSM, AMPS, and Industrial, Scientific, and Medical (ISM) band
applications. The MRFIC0930 is a two–stage low noise amplifier with an
integrated step attenuator and is packaged in a low–cost SO–8 package.
The MRFIC0930DM is packaged in the smaller Micro–8 package. The

attenuator is controlled by a V
Pin. The LNA can be turned off during
gain
transmit mode to save current by using the Rx Enable Pin. The amplifier can
be matched to optimize gain or noise figure with simple off–chip input
matching.
• Usable Frequency Range = 800 to 1000 MHz
