02.07.23 -- Inside The EU's Call For The Regulation Of Space Operations

One major decision a PA module designer must make during development is the choice of architecture utilized in the amplification circuit. The two most widely used options are a monolithic microwave integrated circuit (MMIC) or a design built around discrete components.

Organizations in need of RF/microwave components and microwave subsystems often have difficulty identifying standard catalog solutions that will perform optimally, or even fit adequately, within their systems.

You don’t need to know how to design every RF printed circuit or build MMICs, but you can certainly avoid re-spins and ensure RF signal integrity by understanding these key design points.

Inside a laser system’s fiber optic cabling is a power-limiting challenge known as stimulated brillouin scattering (SBS). Engineers can tackle SBS challenges with additive white Gaussian noise (AWGN) generation during laser weapon design.

The high-power density and high breakdown voltage of GaN-on-SiC make it of particular interest for power amplifiers. This white paper details the design and performance of a 28 V, three-stage, Ka-band, GaN-on-SiC, power amplifier MMIC with high efficiency and low gain.

Recent semiconductor technologies require more of the frequency range beyond 50 GHz, especially in wideband applications, such as 802.11ad, microwave links, or automotive RADAR. Low phase noise is essential for these applications to work properly, and accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise.
