PRODUCTS 37 LNAs for cellular and WiMAX infrastructure improve receiver sensitivity Avago Technologies has announced a family of MMIC low noise amplifiers (LNAs) designed for cellular and WiMAX infrastructure applications, including picocell and femtocell base stations. The family comprises the MGA-12516, 13516 and 14516, all housed in a 4.0 x 4.0 x 0.85 mm 16-pin QFN. MGA-12516 is a matchedpair balanced LNA designed to operate between 800 MHz to 3 GHz. At 4V and 50 mA per LNA, it delivers 0.62 dB noise figure, 23.8 dB gain, 33.5 dBm OIP3 and 17.9 dBm P1dB at 1.95 GHz. The MGA-13516 and MGA-14516 are two-stage LNAs with built-in active bias circuity and the ability to adjust the supply current RF transceiver for ZigBee applications low power operation with 103 dB link budget Texas Instruments has introduced its secondgeneration ZigBee®/IEEE 802.15.4 RF transceiver designed for the 2.4 GHz unlicensed ISM (industrial, scientific, medical) frequency band. Featuring state-of-the-art selectivity/co-existence and excellent link budget, the CC2520 targets a wide variety of ZigBee/IEEE 802.15.4 and proprietary wireless systems used in industrial monitoring and control, home and building automation, set-top boxes, remote controls and wireless sensor networks. In a typical system, the CC2520 will be used together with a microcontroller, such as TI’s MSP430 ultra-low power MCUs, and a few additional passive components. The CC2520 reduces the load on the host controller by providing extensive hardware support for packet handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and packet timing information. Key CC2520 specifications include 1.8 V to 3.8 V supply range, -40 to +125 degrees Celsius temperature range, 103 dB link budget (400 m line-of-sight range with the development kit), 50 dB adjacent channel rejection. The CC2520 provides an easy upgrade path for the CC2420 RF transceiver. www.mwee.com/206901215 and gain through external matching without affecting the noise figure. MGA-13516 is ideal for 400 MHZ to 1.5 GHz, while the MGA14516 is designed for 1.4 GHz to 2.7 GHz frequencies. At 5V, 155 mA, the MGA13516 achieves 0.66 dB noise figure, 31 dB gain, 38 dBm OIP3 and 24 dBm P1dB at 900 MHz. The MGA-14516 delivers a 0.68 dB noise figure, 33dB gain, 38 dBm OPI3 and 24 dBm P1dB at 1.95 GHz. www.mwee.com/207000301 The Skyworks Advantage Extremely high stop-band isolation while maximizing pass-band ﬂatness and minimizing group delay distortion.
