RF & Wireless Products MACOM Expands GaN Portfolio with 90 W Avionics Power Module M/A-COM Technology Solutions Inc. (“MACOM”) announced the newest entry in its portfolio of GaN in Plastic power module products. Optimized for pulsed Avionics applications in the 960 to 1215 MHz band, MACOM’s new 2-stage, fully matched GaN surface mount power module scales to peak pulse power levels of 100 W in a 14 x 24 mm package size. MACOM’s new high gain GaN in Plastic power modules support surface mount technology (SMT) assembly, providing significant cost and process advantages compared to ceramic-packaged flange-mount components. Delivering clear benefits in size, weight and power (SWaP) while enabling high volume manufacturing efficiency, MACOM’s new GaN power modules feature a Land Grid Array (LGA) pattern for enhanced thermal flow and “True SMT” assembly and do not require copper coining or complicated thermal management techniques on the system PC board. Under pulsed conditions, these modules deliver output power greater than 90 W, with 30 dB a typical associated power gain and 60% typical power added efficiency. Supporting 50 V operation and up to 3 ms pulse width/duration for improved signal flexibility, MACOM’s GaN in Plastic power modules reduce overall power consumption and cooling requirements compared to existing options. “The 90 W Avionics module is the latest GaN Module in MACOM’s growing family of fully matched SMT power products,” said Paul Beasly, Product Manager, MACOM. “The ease of application, system benefits and surface-mount automated assembly are of great benefit to the customer, and critically, also improve the time to market for rapidly evolving requirements in aviation and radar applications.” www.macom.com/gan ■ M/A-COM Technology Solutions Holdings, Inc www.macom.com Richardson RFPD Introduces New 700 MHz – 6 GHz Ultra-Low Noise Amplifier from MACOM Richardson RFPD, Inc. announced the availability and full design support capabilities for a new high dynamic range, single-stage MMIC low noise amplifier from M/A-COM Technology Solutions. The MAAL-011078 is designed for operation from 700 MHz to 6 GHz and is housed in a lead-free 2 mm 8-lead PDFN plastic package. The LNA has an integrated active bias circuit, allowing direct connection to 3 V or 5 V bias and minimizing variations over temperature and process. The bias current is set by an external resistor, so the user can customize the power consumption to fit the application. VBIAS can be utilized as an enable pin to power the device up and down during operation. The MAAL-011078 is ideally suited as a first-stage LNA for 3G/4G cellular infrastructure and Wi-Fi applications, including 802.11ac, as well as Aerospace & Defense applications. ■ Richardson RFPD www.richardsonrfpd.com NXDN Radio Fast-Track CML Microcircuits has released an NXDN Processor with embedded Air Interface (AI) Protocol. The CMX7131/7141 with the NXDN Function Image connects directly to the CMX994 Direct Conversion Receiver IC. Together these devices form a formidable chip-set, enabling a fast development cycle for small, highlyintegrated, multi-standard capable digital radios that will exhibit a long battery life. The majority of the NXDN air interface physical layer (layer 1) and data link layer (layer 2) is embedded in the NXDN Function Image plus a host of advanced features to support the complete radio system and simplify the overall radio design process. NXDN is an FDMA digital Land Mobile Radio (LMR) open standard and has evolved to become a key narrowband technology in the LMR migration from analogue to digital. NXDN is supported by more than 25 international radio manufacturers and organisations that together form the NXDN Forum (www.nxdn-forum.com) The new NXDN Function Image adds to the existing suite of CMX7131/7141 function images, now covering dPMR, NXDN, ARIB STD-T98, ARIB STD-T102 and legacy analogue PMR. A radio platform using the CMX7131/7141 can be switched to deliver any of these systems by uploading the appropriate Function Image. This allows radio manufacturers to take advantage of economies-of-scale by adopting a Software Defined Radio (SDR) design route, with one radio design supporting a number of different systems and markets. The DE9944 FDMA SDR Demonstrator is also available, providing the fastest route from development through to production. The CMX7131/CMX7141 processors and function images are available now, offering low power 3.3 V operation in small VQFN/LQFP packaging. ■ CML Microcircuits www.cmlmicro.com 50 hf-praxis 10/2014

RF & Wireless Products TriQuint releases two 100 W Limiters RFMW, Ltd. announces design and sales support for a pair of 100 W VPIN limiters from TriQuint. The TGL2206-SM and TGL2207-SM are available in QFN 5x5 mm surface mount packages for ease of installation in receive protection chains for commercial and military radar systems. The TGL2206-SM covers applications falling from 2 to 5.5 GHz while the TGL2207-SM extends the range from 2 to 6.5 GHz. Both limiters offer 40 dB eliminate the need for a transmit filter. The TriQuint TQM963001 has single-Ended (SE), 50 Ohm downlink & uplink ports for ease of design. Excellent triple beat performance of -88 dBc typifies TriQuint BAW filters as does guaranteed performance over a temperature range of -30 to +85 °C. The TQM963001 comes in a 2.6x2.1 mm SMT package. ■ TriQuint Stocking Distributor RFMW, Ltd. info@rfmw.com www.rfmw.com 2-W amplifier delivers over 40 dB of gain from 1500 to 2700 MHz Freescale Semiconductor claims to offer the first 2-W integrated power amplifier operating with a 5-V supply and delivering more than 40 dB of gain to cover all frequency bands between 1500 MHz and 2700 MHz. The MMZ25333B supports any cellular standard operating at this frequency including GSM, 3G, 4G and LTE. The high gain MMZ25333B is suitable for driver and pre-driver applications in macrocell base stations, and final-stage applications in small cells. The high performance and integration of the PA help customers reduce part counts, streamline supply chains and optimise costs. Further, since the device can be used across multiple platforms and frequency bands, it can be reused from project to project, simplifying supply chain inventory. The MMZ25333B is a multi-stage power amplifier based on InGaP GaAs HBT technology and is housed in an industry-standard 4 mm QFN package. ■ Freescale www.freescale.com hf-praxis 10/2014 51
