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 […]

Sikorsky completes test program


Sikorsky completes test program, delivers first rugged CH-53 King Stallion heavy-lift helicopter to U.S. Marine Corps EST PALM BEACH, Fla. The U.S. Marine Corps can start replacing its aging CH-53E Super Stallion military helicopterfleet with new CH-53 King Stallion rotorcraft from Sikorsky, a Lockheed Martin company (NYSE:LMT), which has delivered the first of an expected 200 rotary-wing aircraft for the Marine Corps’ fleet. The CH-53E first flew in 1974 and entered service with the Marine Corps in 1981. The CH-53K is the new build replacement for the Super Stallion helicopter. The rugged CH-53K helicopter is an all new aircraft with a modern intelligent design intended to […]

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.

GaN-on-SiC RF and microwave transistors


GaN-on-SiC RF and microwave transistors for S-band radar applications introduced by Integra Technologies EL SEGUNDO, Calif. – Integra Technologies Inc. in El Segundo, Calif., is introducing a pair of 135- and a 130-Watt gallium arsenide-on-silicon-carbide (GaN-on-SiC) RF and microwave transistors for S-band radar applications. The IGT2731M130 is a 50-Ohm matched high-power GaN high-electron-mobility transistor (HEMT), supplying a minimum of 130 Watts of peak pulsed power, a gain of 13.5 dB and a drain efficiency of 55 percent, at pulse conditions of 300 microseconds at 10 percent duty cycle. It operates at the instantaneous operating frequency range of 2.7 to 3.1 GHz, and is a depletion mode […]

Air Force invests in origami antenna technology


Air Force invests $4.8M in FIU origami antenna technology for aircraft, UAS, satellites MIAMI. The U.S. Air Force is investing nearly $5 million in origami, or foldable and reconfigurable, antennas to enable new aerospace and tactical systems for communication and sensing in aircraft and satellite applications. Inspired by the Japanese art of paper folding, origami electromagnetic systems include: reconfigurable, foldable, and deployable multifunctional antennas and antenna arrays, adaptable “smart skins” for communication and sensing, and compact/collapsible wearable antennas. Florida International University (FIU) won a $4.8 million grant from the Air Force Office of Scientific Research at Wright-Patterson Air Force Base in Ohio to […]
