RF & Wireless Modules Single-Package Power Supply Modules ROHM has recently announced the development of the BZ6A series of ultra-compact power supply modules that integrate an inductor, capacitors, and all the other components needed for power supply into a single package. The result is a very small size (2.3 mm × 2.9 mm × 1 mm), making RF Micro Devices, Inc. announced the release of the RFFM6201, a 2.4 GHz band single-chip Zigbee front-end module featuring an integrated power amplifier, low noise amplifier, and diversity switch. RFMD‘s 2.4GHz RFFM6201 has a current consumption of 170 mA at rated power and high-power performance of +23 dBm for Home Area Networking (HAN)/Smart Energy applications. The energy efficient RFFM6201 is pin-for-pin compatible with them suitable for high-density mounting applications. The BZ6A series integrates a BU9000X series 6 MHz high-speed switching power supply LSI directly into the board and includes all necessary components in a single package. High performance is ensured in the industry‘s smallest form factor. The all-in-one configuration eliminates the need for external components, simplifying design time. Additional features include a wide input voltage range, from 2. 3 V to 5.5 V, making them suitable portable devices utilizing 5 V USB, as well as an output voltage range between 1.0 V and 3.3 V, ensuring compatibility with a variety of sets. ■ ROHM Semiconductor GmbH www.rohm.com/eu RFMD Expands Portfolio of High Performance 2.4 GHz Front End Modules for ZigBee/HAN Applications HGM and HGV Series Gunn Oscillators RFMD‘s popular RF6555 and offers 5 dB higher output power, enabling customers to increase power output and range without requiring changes in product layout. ZigBee Smart Energy is the world‘s leading standard for home area networks (HAN) used by smart grid programs to boost energy management and efficiency in homes around the world. ■ RFMD https://estore.rfmd.com The HGM and HGV series Gunn Oscillators cover the 7 - 150 GHz frequency range. A wide variety of designs provide solutions for most applications. Units are available with mechanical and/or electrical tuning, providing many possible tuning configurations. Superior frequency and power stability are achieved using cavity designs and optimal diode selection. Heaters can be provided to achieve greater frequency stability. GaAs and InP Gunn diodes are used depending on the frequency and performance requirements. Cavity designs are mated with the proper Gunn diode to maximize performance. Gunn oscillators are used as sources for mixer LOs, to drive multipliers, transmitters, and radars. Options available include voltage regulators, heaters, isolators, heat sinks, and micrometer tuners. ■ Renaissance Electronics Corporation www.rec-usa.com / www.hxi.com hf-Praxis ISSN 1614-743X Fachzeitschrift für HFund Mikrowellentechnik • Herausgeber und Verlag: beam-Verlag 35001 Marburg, Postfach 1148 Tel.: 06421/96140 Fax: 06421/961423 E-Mail: info@beam-verlag.de www.beam-verlag.de • Redaktion: Dipl.-Ing.
