Traditional base-station RF power amplifiers (Figure 1) utilize a variety of different technologies and operating conditions to balance different performance parameters. One of the most common challenges in achieving optimal performance involves finding the balance between linearity and efficiency. The key drivers for balancing linearity with efficiency, in order of importance, are: Determining between GaN, LDMOS, or SiGe as the optimal technology for your device. The specific class of device operation, ranging from Class A, AB, C, or E. Considering the configuration of circuit topology (Single-Ended, Push-Pull, or Doherty). The strategic management of back-off ratios from the P1dB compression point.…

What made you select the XMA Cryogenic Attenuators as featured products? How do these products offer value ? The Cryogenic line of Attenuators from XMA is the epitome of purposeful design. By understanding how the resistive attenuation generates heat in the Quantum Computing environment of millikelvin temperatures, they have chosen materials and structures which disperse the heat through attenuator body rather than the coaxial lines. These components dissipate the generated heat into the immediate environment rather than off-loading it into the coaxial cables to be carried to other chambers and interfering with the Quantum Processor.

What made you select MRC Component’s MRC Rolls as a product to feature? Why is it important that MRC Rolls Suppress Harmful Interference Currents?I selected MRC Rolls to feature because they provide a significant cost and implementation benefit for customers who need to suppress harmful interference currents and reduce radiated emissions.Electric and magnetic fields, or electromagnetic fields (EMF), are linked together and form electromagnetic waves. Activities such as power generation produce EMFs and radiate emissions as a side effect of generation. However, very strong electric and magnetic fields endangers health and life, therefore it is necessary to limit the range…
Quantum computing is one of the most powerful tools developed in the past few decades. Quantum computers (QCs) solve otherwise unsolvable problems in physics and mathematics, all because of the unique properties of their design and construction. To understand why a QC works so effectively we’ll dive briefly into what quantum computing is, why cryogenics are essential in quantum computing design, and what qubits are and how they are used. Additionally, we’ll discuss a critical design piece that doesn’t get talked about as much: the importance of interconnect components in quantum computing designs.If you work in RF and Microwave you…
What made you select TTM Technologies High Reliability Xingers® as the featured products for the month? TTM Technologies has just released a new line of products designed for high-reliability applications that are excellent options for designers working on L-band, S-band, C-band and X-band Radar applications. These Xinger® 90 degree hybrid couplers, directional RF couplers, and power baluns have superior RF performance, including wideband performance and lowest insertion loss. They are designed using “Best Material” developed for high-reliability applications and have an ENIG finish with a long shelf life. Additionally, they are 100% RF tested and individual part test data serializing is…
What made you select Knowle’s new StackiCap MLCC Capacitors? What value do these products offer?Knowles new StackiCap MLCC Capacitors offer unmatched combination of case size, capacitance, and voltage and can significantly reduce PCB space for applications needing high voltage, high capacitance MLCCs. The unique design incorporates a patented sponge layer technology allowing the part to be stacked up while terminated as a single MLCC homogenous design. Typical MLCC material is brittle and subject to cracking due to the piezoelectric, which causes parts to vibrate when current is applied and possibly cracking the MLCC. The sponge layer helps dampen the vibration…
By Tim Daniels, Supplier Business Manager RF PowerPrimary radars are strategically located in various regions to aid air traffic control (ATC) and surveillance. These radars are crucial in monitoring and managing commercial and military aircraft movements.Terminal radar, or airport surveillance radar (ASR), is primarily used near airports and terminals. It usually operates on S or X-band frequencies and accurately covers local air traffic movements, monitoring aircraft during take-off, landing, and low-altitude flights. It helps controllers maintain separation between aircraft and guide them safely through the busy terminal airspace.En-route radar is used for air traffic control in the airspace between airports and…

What made you select the Marki Microwave ADM-8536PSM LNA? I chose Marki Microwave’s ADM-8536PSM because it is the industry’s smallest 2-20GHz high linearity, low noise amplifier. It’s the entire LNA solution, complete with an internal biasing network, DC blocking, and RF matching, all in a tiny, DFN-style package. Add in the low power consumption, the ADM-8536PSM is the ideal choice for reducing SWaP. I also want to highlight this part as a reflection of Marki’s push to expand their selection of offerings well past their industry-renowned mixers. For the past couple of years, Marki has been extensively growing their product…
