Antenova Diversity Kit Uses New Cat4 LTE Standard

Antenova Diversity Kit Uses New Cat4 LTE Standard - RF CafeAntenova, manufacturer of antennas and RF antenna modules for M2M and the Internet of Things, is to show a development kit for a certified Cat4/LTE design at CES2019. LTE Category 4 (Cat4) is the next step in 4G LTE device capability. A Cat4 device uses two antennas - a main antenna for transmit and receive, and a second antenna for receive only. The two antennas radiate in different pattern directions which means they will always provide a good signal in any orientation, as the unit is moved around or turned. The kit gives designers a short cut to a successful Cat4 design and certifications, which can otherwise be difficult to achieve ...

QuinStar Technology Engineer Captures Orion Nebula

QuinStar Technology Engineer Captures Orion Nebula - RF CafeAt QuinStar, we're about more than millimeter-wave technology. The people comprising QuinStar Technology pursue diverse and exciting outside interests. Our Chief Engineer, Jim Schellenberg, is a highly skilled amateur astronomical photographer. He captured this beautiful image of the Orion nebula using a specially modified Canon 6D. The camera responds to the H-alpha spectral line at 656 nm (from hydrogen gas), which is seen as red in the photo. The camera is mounted on an 11-inch telescope that tracks the object as the earth rotates. This image consists of nine one-minute exposures that are "stacked" to form the image you see. This is an excellent time of the year to view the Orion nebula. It can be seen with the naked eye ...

R&S White Paper: An Introduction to EMC Amplifiers

R&S White Paper: An Introduction to EMC Amplifiers - RF CafeFree for your downloading pleasure is Rohde & Schwarz's white paper titled, "An Introduction to EMC Amplifiers." "In order to perform immunity testing on an electronic device, we must subject that device to defined levels of radio frequency energy over a wide range of frequencies and verify that the device continues to function properly. This radio frequency energy may be conducted into a device via its attached cables or be directly picked up 'over - the - air,' i.e. from radiated signals. As we will see, radiated emissions represent the greater challenge in immunity testing. The first reason for this is that radiated immunity (or susceptibility) testing often requires the creation of very high electric field strengths , with typical values ranging from 3-200 V/m. Depending on frequency, distance ..."

Triad RF Systems Intros 30 - 2700 MHz, 8 W Bi-Directional Amplifier

Triad RF Systems Intros a 30 to 2700 MHz, 8 W Bi-Directional Amplifier - RF CafeTriad RF Systems, a top-tier designer and manufacturer of RF and microwave amplifiers, announces the introduction of their TTRM1210 bi-directional amplifier, a wideband GaN Bi-Directional Amplifier (BDA) that operates from 30 MHz to 2700 MHz and produces over 8 W of transmit power. The receive side has over 20 dB of gain to overcome losses between the antenna and the radio. The noise figure is 2 dB which makes the BDA practically invisible to the system. Switching between transmit and receive can be done either automatically when RF is sensed at the radio port, or manually switched by the radio or user. One of the smallest BDAs in the industry measuring only 3.25 x 2.12 x 0.53 inches, this feature rich BDA is also one of the most efficient. While producing 8 W of RF power ...
