| HMC376LP3 / 376LP3E v00.1005 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 700 - 1000 MHz 5 AMPLIFIERS - SMT Typical Applications The HMC376LP3 / HMC376LP3E is ideal for: * Cellular/3G Infrastructure * Base Stations & Repeaters * CDMA, W-CDMA, & TD-SCDMA * Private Land Mobile Radio * GSM/GPRS & EDGE * UHF Reallocation Applications Features Noise Figure: 0.7 dB Output IP3: +36 dBm Gain: 15 dB Externally Adjustable Supply Current Single Positive Supply: +5.0V 50 Ohm Matched Input/Output Functional Diagram General Description The HMC376LP3 & HMC376LP3E are GaAs PHEMT MMIC Low Noise Amplifiers that are ideal for GSM & CDMA cellular basestation front-end receivers operating between 700 and 1000 MHz. The amplifier has been optimized to provide 0.7 dB noise figure, 15 dB gain and +36 dBm output IP3 from a single supply of +5.0V. Input and output return losses are 14 and 12 dB respectively and the LNA requires only one external component to optimize the RF Input match. The HMC376LP3 & HMC376LP3E share the same package and pinout with the HMC382LP3 1.7 - 2.2 GHz LNA. The HMC376LP3 & HMC376LP3E feature an externally adjustable supply current which allows the designer to tailor the linearity performance of the LNA for each application.
