A high-efficiency 750W RF power transistor has been announced by Ampleon, with the BLF0910H9LS750P, which has a high efficiency of 72.5% at 915MHz and a rugged design. The device operates at frequencies from 902MHz to 928MHz making it suitable for use in industrial, scientific, and medical systems, as well as for professional cooking applications.

The device’s high efficiency minimises the amount of energy it uses to deliver a given output power, reducing operating costs, decreases heat dissipation, enabling simpler and lower-cost cooling solutions, more compact systems, and hence lower manufacturing costs.

The BLF0910H9LS750P’s rugged design enables the device to withstand a load mismatch equivalent to a VSWR (voltage standing wave ratio) of 10:1, through all phases. This enables users to simplify their system designs and employ less sophisticated circuit-protection mechanisms, reducing the end product’s bill of materials and so improving overall manufacturing yield.

The device’s pre-matched input makes integration easier into end applications. Its broadband capabilities enable better control and flexibility in operation.

The BLF0910H9LS750P is built on Ampleon’s Gen9HV 50V process, which has the maturity to ensure high levels of product consistency that, coupled with comprehensive application support, will help end-equipment manufacturers reduce the time they need to bring their products to market.

The BLF0910H9LS750P is available now, from Ampleon and distributors including Digikey and RFMW.
