Low Loss, High Isolation mmWave Switch MMICs

by Graham Pearson and Liam Devlin, Plextek RFI Many emerging applications at Ka-band and above, such as 5G and broadband satellite communications, are adopting architectures that require low-loss, high-linearity switches. FET-based switches on both GaAs and SOI (Silicon on Insulator) are used to realize high performance, low-loss switches at RF frequencies. They have been used […]

VFTT – Plextek RFI

Liam Devlin, CEO, Plextek RFI MPD: The 2019 defense budget is chock full of EW, radar, and other programs with lots of RF and microwave content, so, if your company serves the defense market, what are your thoughts about how this will affect your business in the coming years? LD: Government defense system orders generally […]

The Design of Multi-Chip SMT Front-End Modules for mm-Wave 5G Applications

by Graham Pearson*, Liam Devlin* and Mike Geen†, *Plextek RFI Ltd and †Filtronic Broadband Ltd The order-of-magnitude increase in data rates, and seemingly infinite capacity, promised by 5G communications systems will be facilitated by the use of mm-Wave frequencies, where large bands of contiguous spectrum are being made available. Although the mm-Wave bands for 5G […]

VFTT – Plextek RFI

Liam Devlin, CEO, Plextek RFI MPD: Millimeter wave frequencies will be used for cellular communications for the first time in 5G. What challenges and opportunities does this present for the microwave industry? LD: We have developed mmWave components for most of the favored candidate mmWave 5G bands (26 GHz, 28 GHz, 37 GHz and 39 GHz). The […]

Design of a Broadband L-band 160W GaN Power Amplifier Using SMT Packaged Transistors 

by  Plextek RFI & Qorvo The design of a broadband power amplifier for L-band radar and wideband communications applications is described. Using a state-of-the-art Qorvo transistor in a cost-effective SMT plastic package, the amplifier has 160W output power between 1.2GHz and 1.8GHz and a typical efficiency of 55% for the complete connectorized PA. Particular consideration […]

Mm-wave Components and Technologies for 5G Applications

Plextek RFI CEO Liam Devlin speaking at the Interlligent RF & Microwave Seminar 2017. With work well under way on the design and development of the first mm-wave 5G demonstrator system, a much quoted goal is to have a network capable of providing seemingly infinite capacity and negligible latency. Operation at mm-wave frequencies allows the […]

View From the Top – Plextek RFI

by Liam Devlin, CEO – Plextek RFI MPD: The defense market for RF and microwave components through subsystems appears to be more lucrative than in recent years, especially in the area of electronic warfare. If your company sells into the defense market, what are your thoughts about how it will perform in 2017? LD: The defense market is […]

Design and Evaluation of a 125W L-Band GaN Power Amplifier

by Andy Dearn and Robert Smith – Plextek RFI The scope and performance of commercially available Gallium Nitride (GaN) discrete transistors is steadily increasing and the parts now available from leading manufacturers have impressive RF performance in terms of their available gain, RF output power and efficiency. For RF output powers in the order of […]

The Design of an L-band 125W GaN PA

Plextek RFI has published a new white paper on its website, entitled ‘The Design of an L-band 125W GaN PA‘. The white paper describes the design and evaluation of a single stage 125W L-Band GaN Power Amplifier using a low-cost packaged transistor. The amplifier is optimized for the 0.96 to 1.215 GHz band with a […]
