RFMW announces design and sales support for a WiFi 6 (802.11ax) front end module (FEM). The energy efficient Qorvo QPF4288 integrates a 2.4 GHz power amplifier (PA), regulator, SP2T switch, bypassable low noise amplifier (LNA) and coupler into a single device. Optimizing the internal PA for 5V operation while maintaining linear output power and leading-edge throughput, the QPF4288 offers 33 dB of transmit gain and 15.5 dB receive gain with 1.7 dB noise figure. The receive path is pinned out so external filtering can be added in the optimal position while filtering for 2nd and 3rd harmonics as well as…

RFMW announces a micro-site for customers and suppliers supporting solid-state RF energy technology. Magnetron tubes have dominated this market but have drawbacks with regards to degradation, reliability and power control. Solid-state RF solutions can be used to replace existing magnetron-based systems. Generally, magnetron replacement systems are made up of 1KW modules, some systems can reach 50-60 Kilowatts at their final output. Solid-state RF energy offers a number of advantages including precise power/frequency/phase and PWM control, high-speed arc detection & shutdown, stability at all power levels, no degradation of power with age, improved reliability and the use of lower voltage power…
