Cree Semiconductor Re-Enters High-Power RF Transistor Market SUMMARY HED: Gallium nitride transistors deliver 300 Watts at 2.7 GHz At the start of the DTV transition, Westinghouse and Cree partnered ...

High-power broadcast-TV transmitter design should become easier with the MRF6P3300H enhancement-mode MOSFET. Designed for use in TV transmitters of 1, 5, and 10 kW, it can dissipate up to 300 W. It's ...

Rohde & Schwarz’s transmitter plant in Teisnach, Germany Readers who have followed my RF Technology column for the last 20 years may have noticed that I started out saying that solid-state amplifiers ...

Component distributor Richardson RFPD has prepared a couple of documents on the options available for designers of RF amplifiers. Rather than in-depth, they are a useful introduction to the different ...

RF power amplifiers are going wide and high to meet wider frequency ranges and the need for more bandwidth. Many wireless electronic systems operate over wide frequency ranges and the need for more ...

Imec researchers have set a new benchmark in RF transistor performance for mobile applications. They present a gallium nitride (GaN) MOSHEMT (metal-oxide-semiconductor high-electron-mobility ...

It all started when the phone rang. A fairly savvy radio operations manager was at a site with a sick FM transmitter, a Continental 816R-2C 20 kW transmitter with a tube power amplifier, solid-state ...

There are a multiplicity of transmission modes both new and old at the disposal of a radio amateur, but the leader of the pack is still single-sideband or SSB. An SSB transmitter emits the barest ...
