2W power amplifier reduces design time and costs
Covering all frequency bands between 1500 and 2700MHz, the MMZ25333B 2W integrated power amplifier has been introduced by Freescale. The amplifiers operate with a 5V supply and deliver more than 40dB of gain, supporting any cellular standard operating at this frequency - including GSM, 3G, 4G and LTE.
VCO operates across 200-239MHz frequency range
The CVCO55FL-0200-0239, a VCO which operates across a 200-239MHz frequency range with a control voltage range of 0.5-4.5V, has been introduced by Crystek. This features a typical phase noise of -123dBc/Hz at 10KHz offset and has an output power of +8.5 dBm.
Family of 25, 50 and 100W attenuators are introduced
A family of 25W, 50W and 100W attenuators have been introduced by Fairview Microwave. The family, numbering 236 devices, feature 3, 6, 10, 20, 30, 40, 50 and 60dB attenuation options, and can be ordered with SMA, TNC, Type-N and 7/16 DIN in-series connector configurations. The attenuators also come in each gender interface, including male-male, male-female and female-female.
SDR prototyping kit allows for multi-channel synchronisation
A SDR rapid prototyping kit, billed as the industry’s first, has been released by Analog Devices. Incorporating dual 2 x 2 AD9361 RF transceivers, the AD-FMCOMMS5-EBZ kit aims to simplify and rapidly prototype 4 x 4 MIMO wireless transceiver applications on the Xilinx Zynq-7000 all programmable SoC development platforms.
Digitally tunable filters boost tactical-radio performance
The new TF010x series of digitally tunable bandpass filters from Link Microtek offer military communications systems designers a low-loss frequency-hopping capability for software-defined radios. Designed and manufactured by MtronPTI, the filters are available in eight different models covering frequency ranges from 30MHz to 1GHz, each with 250 tuning steps, 8-bit parallel tuning control and a switching time of less than 25µs.
Low jitter clocks are the industry’s most frequency-flexible
Comprising high-performance clock generators and highly integrated multi-PLL jitter attenuators, Silicon Labs has announced the next-generation Si534x 'clock-tree-on-a-chip' portfolio. They are claimed to be the industry’s most frequency-flexible clock solutions offering industry-leading jitter performance for high-speed networking, communications and data centre equipment in internet infrastructure.
Crystal series offers 43% improvement in total tolerance
A series of crystal units for use in a broad range of consumer and industrial applications has been released by Murata. Based on the company's XRCGB-F family, the XRCGB-F-P crystal units have an improved frequency tolerance of +/- 20 ppm (at +25°C) and an improved frequency shift by temperature of +/- 20 ppm max. (-30 to + 85°C).
RFID transponder operates from -50 to +160°C
A RFID transponder suitable for use in harsh environments, has been released by HARTING. Due to its combination of robustness, high protection and resistance to high temperatures, the Ha-VIS RFID VT 86 (HT) performs particularly well in harsh environments. The transponder measures 41x11x5.15mm, has a memory of 3kB and an operating temperature of -50 to +160°C.
Multi-stack radio chips support IEEE 802.15.4 protocol
A series of patented multi-stack low-power radio chips, which support Thread's IEEE 802.15.4 MAC/PHY protocol, have been released by GreenPeak Technologies. This is an IoT and Smart Home standardisation effort, as many other manufacturers within the industry are supporting this protocol, along with a 2.4GHz band, which the GP71x series also supports.
PCIe clock buffers reduce size and power consumption
Expanding the company's PCIe timing portfolio, Integrated Device Technology has introduced what it claims to be the industry’s first 1.5V PCI Express (PCIe) buffer family. Operating from the same supply voltage as modern SoCs and FPGAs, the 9DBU buffers allow designers to use the same power rail. This reduces system complexity, physical size, and power consumption.
