We are now living in an increasingly digitally driven society where reliable Wi-Fi is a key aspect of everyday life, and this is true whether you are at home, or on the move. The rail passengers of today expect the same connectivity on-board as they do when relaxing at home. They want to work, communicate, or stream movies while travelling by train, causing more and more demand for higher data throughput rates. 

According to the U.S. Bureau of Transportation Statistics, 2020 was the fifth consecutive year of growth in electric vehicle (EV) sales, and the demand is growing. Based on the first quarter numbers, the Bureau anticipates 2021 sales are on a path to surpass last year’s. 

As you already know, capacitors are essential circuit elements for storing and suppling charge on demand. For inductors and resistors, capacitors act as the building blocks of passive circuits and the supporting components for active circuits. While a wide range of fixed-value capacitors are used in most electrical circuits, it is sometimes preferable, or necessary, to use a component with a variable capacitance range.

NuWaves Engineering offers the NuFilter™ series of cavity filters designed for applications operating within the 1 GHz to 20 GHz frequency range. Options for standard and custom models include 3 dB bandwidths from 3% to 28%, stop-band rejections of 80 dB, insertion losses of < 1 dB, and up to 50 W power handling (higher power ratings available upon request).

The QPL9504 is a flat gain, high-linearity, ultra low noise amplifier in a small 2 x 2 mm surface-mount package. At 5.5 GHz, the amplifier provides 0.7dB noise figure with 21.5 dB gain and +34 dBm OIP3 while drawing 55 mA bias current.

The VTA-6430A Series are 500W CW Coupled Cavity TWTs covering 27.5 - 31.0 GHz (Ka-Band) with 2 GHz instantaneous bandwidth, periodic-permanent-magnet focused, wave-guide input, waveguide output, conduction cooled. This high-efficiency CC TWT is designed for use in satellite communication amplifiers.

Knowles' latest enhanced range of Safety Certified capacitors complies with international UL / cUL and IEC/EN specifications to offer designers the option of using a surface mount ceramic multilayer capacitor to replace leaded film types.
 

Corry Micronics' Broadband Diplexer is capable of filtering input power up to 150 WATTS CW. The low and high passbands can be specified by the customer. Temperature range, heat sink requirements, and input power can be customized for each application.
