Ampleon Extends LDMOS Base Station and Multi-Carrier Line with 400W Rugged Doherty RF Power Transistor

October 27, 2021 by Hailey Stewart

The BLC10G27XS-400AVT offers excellent rugged characteristics, up to a VSWR of 10:1, considered essential for base station applications where high-power extreme mismatch conditions can often occur.

Ampleon today announced the introduction of the BLC10G27XS-400AVT 400-Watt asymmetric Doherty RF power transistor. Designed for use in base station multi-carrier applications operating in the 2.496 GHz to 2.690 GHz frequency range, the -400AVT uses Ampleon's industry-respected 9th generation 28 V LDMOS process technology. Fabricated in an air cavity plastic (ACP) earless SOT-1258-4 package, the Doherty transistor typically delivers a drain efficiency of 45%.

The transistor has integrated ESD protection, has a low output capacitance that improves Doherty performance, and includes internal input and output impedance transformation, enabling user-friendly PCB matching to 50-ohm. The power gain specification of the BLC10G27XS-400AVT is typically 13.3 dB based on quoted test conditions. Additionally, the -400AVT has low thermal resistance attributes that yield excellent thermal stability for demanding base station applications.

Design support resources for the BLC10G27XS-400AVT include a recommended driver, the BLM9D2327S-50PB, an LDMOS 2-stage integrated Doherty MMIC, and the PCB layout for a Doherty production test circuit.

The Ampleon website hosts the BLC10G27XS-400AVT datasheet, application notes, simulation models, and an RF power transistor lifetime calculator.

The BLC10G27XS-400AVT is now available from approved Ampleon distributors, RFMW and DigiKey.
