Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced two new Bypass Low Noise Amplifiers (LNAs) which are ideal for applications in Telematics, Broadband, WiMAX, WiBro and Fixed Wireless bands from 2.3 to 3.8 GHz. The HMC605LP3(E) and the HMC593LP3(E) are GaAs pHEMT MMIC Bypass LNAs which are rated from 2.3 to 2.7 GHz, and 3.3 to 3.8 GHz respectively. These wide dynamic range LNAs deliver noise figure as low as 1.0 dB, output IP3 as high as +29 dBm, and up to 20 dB gain. Both LNAs feature an integrated bypass path which exhibits only 2 dB loss, making them ideal for infrastructure and subscriber applications in Telematics, Broadband, WiBro, WiMAX, and Fixed Wireless systems. The HMC605LP3(E) and the HMC593LP3(E) operate from a +5V supply, and are switched between LNA mode and Bypass mode via a single, CMOS compatible, 0/+5V control line. These compact LNA MMICs require no external matching components, incorporate DC blocked RF I/Os, and are housed in pin compatible and RoHS compliant 3x3 mm QFN SMT packages. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
