GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 1.7 - 2.2 GHz
Features
Noise Figure: 1 dB Output IP3: +30 dBm Gain: 17 dB Externally Adjustable Supply Current Single Positive Supply: +5V 50 Ohm Matched Input/Output
General Description
The HMC382LP3 & HMC382LP3E high dynamic range GaAs PHEMT MMIC Low Noise Amplifiers are ideal for GSM & CDMA cellular basestation front-end receivers operating between 1.7 and 2.2 GHz. This LNA has been optimized to provide 1.0 dB noise figure, 17 dB gain and +30 dBm output IP3 from a single supply of +5V. The HMC382LP3 & HMC382LP3E feature an externally adjustable supply current which allows the designer to tailor the linearity performance of the LNA for each application. For applications which require improved noise fi gure, please see the HMC618LP3(E).
