Referencedesign til RF-baseret madtilberedning
Ampleon står bag referencedesign til et 250Watt 2,4 - 2,5 GHz system til RF-baseret madtilberedning og industrielle opvarmnings-applikationer (in english).
Ampleon has announced the availability of a 250 Watt 2.4 – 2.5 GHz amplifier reference design. Believed to be the world’s smallest 250 Watt design, the MicroBlaze 250 measures just 80 x 40 x 5 mm, and is ideal for use in RF cooking and industrial heating designs where power controllability and a modular design approach are key criteria.The LDMOS-based MicroBlaze 250 is fabricated on a copper base plate using cost optimized PCB materials and uses Ampleon’s BLC2425M9XS250 ACP-3 air cavity package and BLP27M810 power transistors. It is fully balanced in terms of gain and power efficiency and is a ready-to-copy amplifier reference design that can be incorporated into an end product. Full optimized for BOM cost, customers can gain a significant time-to-market advantage by using this reference design in their application.
With a 21 dBm input the MicroBlaze 250 provides a 36 dB gain and a 250 Watt output measured at P1dB compression. The module has a rugged VSWR characteristic and can sustain 60 seconds up to 10:1. It is powered from a + 32 VDC supply and consumes 20 Amps. Capable of operating in most environments it has an operating temperature range of + 5 to + 100 degrees C.
