HASCO Building a Complete Line of Millimeterwave Components

Click Here to View our Newest Millimeterwave Components Waveguides are a special form of transmission line used for microwave applications. They are metallic tubes made often of high quality material (copper, brass – partially silvered or gold plated). A waveguide may have rectangular, circular or elliptical cross section. The rectangular waveguide is most commonly used for relatively short connections. Waveguide has a number of advantages over coax, microstrip and stripline. It is completely shielded , it can transmit extremely high peak powers and it has very low loss at microwave frequencies. The main advantage is that waveguides support propagation with […]

Robust RFID Tags Track Firearms

New laws are calling for the dependable tracking of firearms, and modern RFID tags can be integrated with the metal components of firearms to monitor the use of guns. Ron Marino | Jun 20, 2018 Firearms are constantly subjected to regulations and legislation in attempts to control access and limit operation only to authorized users. Many efforts have been made to track the critical components of a firearm throughout its operating lifetime, with one of the most critical firearm components referred to as the receiver. The receiver contains the trigger and the bolt. The receiver is often the only portion of a […]

Conference on Millimeter and Terahertz Waves

The 2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2018), Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2018) held from 9th to 14th, September, 2018 in Nagoya Congress Center, Nagoya, Japan. The conference offers an excellent chance for interaction among participants, as well as the companies providing hardware, software, services, etc. on sciences and technologies of IRMMW-THz and related products. Based on the statistics of the past IRMMW-THz conferences, hundreds of researchers in this field are expected to participate. We strongly encourage the companies to be a sponsor or an exhibitor, an indispensable part of the conference, to […]

Pentek Quartz board taps Xilinx RFSoC FPGA

Pentek Quartz board taps Xilinx RFSoC FPGA to enhance resource integration, connectivity for radar, EW, DRFM May 21, 2018 By Courtney E. Howard Chief Editor, Intelligent Aerospace UPPER SADDLE RIVER, N.J. Pentek Inc. in Upper Saddle River, New Jersey, is introducing the first product in its Quartz Architecture family: the Model 5950 eight-channel A/D and D/A converter, 3U OpenVPX board based on the Xilinx Zynq UltraScale+ radio-frequency system on chip (RFSoC) field-programmable gate array (FPGA). The low-latency benefits of the Quartz architecture support digital RF memory (DRFM) and radar applications that were previously not possible with earlier generation products, officials say. “The Zynq Ultrascale+ RFSoC FPGA […]

Massive-MIMO Hybrid Beamforming

Algorithms to Antenna: Massive-MIMO Hybrid Beamforming Hybrid beamforming can be a practical option when it comes to massive-MIMO systems. This post examines the technology and the techniques employed for both multi-user and single-user systems. Rick Gentile I would like to build on my previous blog discussions related to hybrid beamforming, but this time I will look at how hybrid beamforming can be implemented in a massive-MIMO system. To start with, I will focus on hybrid beamforming at the transmit end of a massive-MIMO communications system, including techniques for both multi-user and single-user systems. We can then partition the resulting precoding […]

Wireless Bandpass Filters – Metamaterials

MATERIALS Wireless Bandpass Filters Build on Metamaterials These second- and third-order bandpass filters leverage metamaterial resonators for low passband insertion loss and high out-of-band rejection for wireless applications at 2.4 GHz. Ahmed A. Ibrahim, Mahmoud A. Abdalla, Adel B. Abdel-Rahman 1 | May 18, 2018 Download this article in PDF format. Microwave bandpass filters (BPFs) are essential for maintaining separate channels in wireless communications systems. As such systems become more compact, BPFs must meet more demanding requirements for smaller size, lower insertion loss, higher out-of-band rejection (selectivity), and lower cost. Several techniques are used to design microwave BPFs,1-4 although the authors have developed an approach […]

Transparentize Connections for 5G Testing

Transparentize Connections for 5G and WiGig Testing As applications reach higher frequencies, the right tools are needed to develop effective connector interfaces. Bill Rosas Download this article in PDF format. Critical to many new projects is a transparent interface to the board—one that you do not even notice is there. This connector-to-board interface is referred to as the board “launch,” where the RF energy transitions from the connector to the board. Figure 1 shows a typical design with 2.92-mm interface 40-GHz connectors on the edge of the board. 1. Shown is a 1:16 Wilkinson divider design that utilizes 2.92-mm connectors. For designers […]

HASCO RF and Millimeter Wave Terminations

HASCO offers a large selection of RF and Millimeter Wave terminations up to 170 GHz Understanding Terminations or Loads RF loads or terminations are indispensable components in many RF and Millimeter Wave systems where signal reflection from unused ports can potentially damage the device or reduce the signal integrity. By using a termination on an unused port with a matched load (dummy load), the incident energy will be absorbed with minimal reflection. These termination components are commonly used to terminate devices such as couplers, circulators, and switches. They are also widely used in measurement systems to ensure accurate results.
