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
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
• 19 dB Typ Gain
• Gain Attenuation = 18 dB (Typ)
• 1.7 dB Typ Noise Figure
• Simple Off–chip Matching for Maximum Gain/Noise Figure Flexibility
• High Reverse Isolation = 41 dB (Typ)
• Low Power Consumption = 24 mW (Typ)
• Single Bias Supply = 2.7 to 4.5 V
• Low Standby Current = 20 µA (Typ)
• Low Cost Surface Mount Plastic Package
