Ampleon extends isolator-free sub-6 GHz line-ups with compact multistage Doherty MMIC drivers for 5G NR and 4G LTE Macro base station applications

Ampleon utilizing advanced LDMOS transistor technology introduces B11G1822N60D, B11G2327N70D and B11G3338N80D as 1^st released series of push-pull multistage fully integrated Doherty RF transistors in new GEN11 Macro driver family covering all sub-6 GHz frequency bands. The released highly efficient multiband devices facilitate the key 5G NR mid-band operation, enabling implementation of next -generation high power and market leading efficiency macro base stations.

The driver product family comes in PQFN 12x7 mm² push-pull packages, which eliminates the need for an interstage isolator. High level of device integration significantly simplifies the design process, reduces BOM cost and assures reliability and volume consistency. The compact pin-to-pin compatible footprints for sub-6GHz bands minimizes the layout work, which is essential for today’s space-constrained applications.

The Doherty transistors typically deliver a drain efficiency exceeding 20 % at 12 dB power back-off and more than 30 dB power gain at the quoted test conditions. Additionally, the designs integrate ESD protection and a bias gate switching.
