RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Why this webcast is important:
The use of over-molded SMT plastic packaging greatly simplifies handling and assembly and reduces unit cost. However, as operating frequencies and RF output power increase, so do the challenges of using SMT packaging. This webcast describes the design of power amplifiers (PAs) at X-band using plastic packaged SMT GaN transistors. The design approach is illustrated with a detailed description of the design, layout, EM simulation, fabrication and evaluation of a single stage 5W X-band GaN PA. The amplifier is optimized for the 9.3 to 9.5 GHz band, has 11 dB small signal gain and provides more than +37 dBm output power at 3 dB gain compression with a corresponding drain efficiency of greater than 55%. The design is based on a commercially available discrete 0.25 µm GaN transistor (the TGF2977-SM from Qorvo) mounted on Rogers 4003 PCB. Fast drain switching circuitry is also included on the same PCB to facilitate pulsed operation with a turn-on time of just 20ns.
Who should view:
Developers of high power solid-state PAs or systems houses who make use of high power solid-state PAs. We look forward to your participation.
