Part 1 of this FAQ looked at the context and the need for waveguides; Part 2 looks at the implementation and available components. Q: What standard waveguide are available? A: There are thousands of models, configurations, and options. Most waveguides have flanges so they can be connected to create longer guides, or to provide turns […]
What are RF waveguides? Part 1: context and principles
Waveguides confine and covey electromagnetic energy in the GHz+ range, just as coaxial cables do; they offer lower loss and other virtues, but at a cost in parts and ease of use. Waveguides (sometimes spelled out as wave guides) do not have the visibility or convenience of coaxial cables but they are an essential passive […]
RF switches, Part 1: Mechanical and PIN-diode switches
There’s a ubiquitous and increasing need to switch RF signals ranging into the tens of GHz; four basic switch technologies – electromechanical, PIN diode, analog, and MEMS – are available, each with different features and capabilities. The need to switch RF signals has been a necessary design function since the earliest days of “wireless.” This […]
RF switches handle 20 GHz with low insertion loss
Menlo Micro announced that it is sampling their MM51xx series of products. These new products, which operate at high power with ultra-low RF losses, and in a miniaturized surface-mount package, bring significant performance improvements as compared to electromechanical and solid-state RF switches. The MM5130 SP4T switch is designed to handle power levels up to 25W […]
Input-protected, low-noise amplifiers handle 1-W CW inputs
Pasternack has released a new line of input-protected low-noise amplifiers (LNA’s) with no damage up to +30 dBm CW input power that are ideal for radar systems, EW applications, military/microwave radios, wireless and satellite communications and test instrumentation. Pasternack’s new line of input-protected low-noise amplifiers consists of 12 different models that cover a broad range of frequency […]
Programmable attenuators offer precision stepped attenuation
Fairview Microwave Inc. has introduced a new line of relay controlled programmable attenuators that offer accurate and stable performance with very low harmonic distortion (IMD) and cover multiple RF frequency bands down to DC. They are popular for use in military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, […]
Waveguide-to-waveguide transitions deliver minimal loss and VSWR as low as 1.08:1
Fairview Microwave Inc., an Infinite Electronics brand, has launched a new line of waveguide transitions that operate from 5.85 to 110 GHz across 14 frequency bands. These waveguide adapters are ideal for high power wireless applications such as test benches, instrumentation, MILCOM, SATCOM, telecom and radar applications where signal strength and integrity are critical. Fairview’s […]
PHY transceivers expand Ethernet connectivity options
Texas Instruments today introduced two new Ethernet physical layer (PHY) transceivers, expanding connectivity options for designers of both space-constrained applications and time-sensitive networks (TSNs). The DP83825I low-power 10-/100-Mbps Ethernet PHY has a 44 percent smaller package size than competing devices and provides a 150-meter cable reach. The DP83869HM is the industry’s only gigabit Ethernet PHY […]
Gain blocks extend the performance of space-qualified InGaP amplifier technology to the X-band
Teledyne e2v HiRel, part of the Teledyne Defense Electronics Group, announces the availability of the new 14 GHz family of RF gain blocks spearheaded by an 18.4 dB amplifier (TDGB014-003). The Gain Blocks are based on an indium gallium phosphide (InGaP) technology that is suitable for use in aerospace and defense applications because of its ceramic […]
Next-gen laminates improve insertion loss in automotive radar sensor applications
Rogers Corporation announced the latest addition to its RO3000 Series PTFE circuit materials: RO3003G2 high-frequency laminates. RO3003G2 laminates build on Rogers’ RO3003 platform to provide radar sensor designers with improved insertion loss and reduced dielectric constant (Dk) variation. The combination of our optimized resin and filler content along with the introduction of Very Low Profile ED […]
