Linear Technology announces the LTC3107, a highly integrated DC/DC converter designed to extend the life of a primary battery in low power wireless system networks (WSNs). The LTC3107 combines energy harvesting and power management capability with a primary battery cell to extend the battery’s usable lifetime. The LTC3107 harvests energy from thermoelectric generators (TEGs) and thermopiles when these sources are available.
TEGAM Inc., a leading supplier of innovative RF power measurements, was recently awarded Patent No. 8,610,069, “Coaxial to Dual Co-Planar Waveguide Launcher for Microwave Bolometry,” This patent describes a new way to construct bolometers—a type of microwave power sensor that uses thermistors—that makes them more accurate and easier to assembly.
RFMW Ltd. announces application and sales support for the Telemakus TEP2000-4 digital phase shifter. This laboratory quality phase shifter has a minimum phase range of 360 degrees with 12-bit, 0.25 degree resolution and operates over the bandwidth of 1 to 2 GHz. Maximum RF input for linear operation is +6 dBm but the device can handle up to +20 dBm.
Dr D.A.S. © prescribes MECA’s low PIM (-160 dBc Typ) compact reactive splitter for DAS applications. Covering 1.700 to 2.200 GHz make them ideal for space restricted areas where the traditional T styles simply won’t fit.
Designed to MIL-F-15733, this small size capacitor is a recommended option to the 74 series capacitor where pin spacing and other clearances allow. Installation is easier and performance is equally robust. These aluminum compatible devices are mountable on .145 inch centers or greater. Full MIL temperature range -55° C to +125° C.
The NI PXIe-7975R FPGA module features a digital signal processing (DSP)-focused Xilinx Kintex-7 FPGA and 2 GB/s of onboard DDR3 DRAM. This FPGA incorporates 1,540 DSP slices, which you can use to implement digital filters, custom signal processing, and fast Fourier transform (FFT) logic, all of which are commonly found on analog FPGA-based instruments.
The TEGAM Model 2191A ± 40 VDC bias adapter was designed to work with TEGAM’s 3525 and 3550 LCR meters to enable accurate testing of electrolytic, tantalum and other polarized capacitors. The 2191A adapter accepts an external DC bias voltage up to ± 40 VDC to be applied across the test capacitor. Four six inch BNC cables are provided to connect the bias adapter to the LCR meter.
Reactel part number 5LM-X1582-T11 filter passes 1164 to 1582 MHz while holding attenuation of greater than 20 dB in the Iridium band of 1616 to 1626.5 MHz. This unit can be fitted with most any RF connector of your choosing.
Reactel part number 4R9-2000-X4S11 is an ultra-narrowband notch filter which utilizes a unique design to achieve a percent bandwidth of less than 0.8%. Attenuation at the center of the notch approaches 90 dB while insertion losses in the Pass-bands are less than 0.75 dB.
Reactel part number 6CX9-1621.25-X10.5T11 is a cavity Band-pass filter for the Iridium band. This unit is specifically designed with a narrow bandwidth and high rejection to isolate Iridium frequencies from outside interference due to Inmarsat systems. This unit can be outfitted with any RF connector you may desire.
