PRODUCTS 39 5 GHz amplifier for WLAN and WiMAX applications offers world-class EVM performance RF Micro Devices has released the SZP-5026Z, a 5 GHz high linearity ampliﬁer designed speciﬁcally for use in WLAN and WiMAX consumer premises equipment (CPE), access point, and base transceiver station (BTS) applications. The SZP-5026Z is a 2 W single stage Class AB Indium Gallium Phosphide (InGaP) Heterojunction Bipolar Transistor (HBT) ampliﬁer optimized for use as either a ﬁnal or driver stage in WiMAX equipment. It delivers worldclass error vector magnitude (EVM) performance of 2.5 percent at 25.5 dBm output power. Technical features include 3 to 5 V supply, operating frequency range of 4.9 to 5.9 GHz, internally pre-matched input and output, integrated input power detector and on/off power control, 1000 V Class 1C ESD protection, and a proprietary, thermally enhanced SOF-26 package. www.mwee.com/207403235 Multi-mode baseband IC multi-core DSP architecture Chip designer Wavesat has made available a new multicore DSP architecture capable of handling baseband processing for multiple broadband networks. The Odyssey 8500 can tackle WiMax Wave 2, 802.11bg and next-generation Personal Handyphone networks. The company will add support for Long Term Evolution cellular in its next generation. The chip designer will supply the physical-layer software to handle the different networks on its bank of eight DSPs, using the IEEE 802.21 spec for medium independent handoff. The company licensed an audio DSP core that it has modiﬁed to handle orthogonal frequency division multiplexing. Most user programming will be handled on a 400 MHz PowerPC core embedded on the Odyssey. The chip is made in a 90 nm embedded DRAM process at IBM and includes 4 Mbytes DRAM, eliminating the need for external memory. Odyssey can run WiMax Wave 2 at speeds and power consumption as low as 100 MHz and 150 mW. The chip is sampling now, will be in production in the fall and is being tested with carriers including Sprint and Vodaphone. The potential for supporting both WiMax and cellular is driving Wavesat’s long-term ambitions. But short-term it also sees promise using its architecture for the nextgeneration Personal Handyphone System that Japan carrier Willcom is expected to deploy in April 2009. www.mwee.com/207801175 Microwave Engineering ● June 2008 ● www.mwee.com http://www.mwee.com/207403235 http://www.dowkey.com http://www.dowkey.com http://www.mwee.com/207801175 http://www.mwee.com
