491LP3E

HMC491LP3 / 491LP3E v03.1206 GaAs MMIC LOW NOISE AMPLIFIER w/ BYPASS MODE, 3.4 - 3.8 GHz 8 LOW NOISE AMPLIFIERS - SMT Typical Applications The HMC491LP3 / HMC491LP3E is ideal for: • Wireless Local Loop (WLL) • Fixed Wireless Access • Microwave & VSAT Radios Features Gain: 16 dB Noise Figure: 2 dB Single Supply: +3V @ 9 mA Integrated Bypass Mode 50 Ohm Matched Input/Output 3 x 3 x 1 mm QFN SMT Package Functional Diagram General Description The HMC491LP3 & HMC491LP3E are versatile, integrated, Low Noise Amplifiers (LNA) featuring a bypass mode intended for 3.4 to 3.8 GHz Fixed Wireless & WLL applications. The amplifier provides 16 dB of gain, 2 dB noise figure and +3 dBm input IP3 while requiring only 9 mA from a +3V supply. Using a single control line, the LNA can be switched into a low loss 2.2 dB bypass mode reducing the current consumption to 20 μA. A low cost, leadless 3x3 mm QFN surface mount package (LP3) houses the amplifier. No external RF matching components are required.
