Introduction

The BLM9D1822-30B is a two-stage fully integrated Doherty MMIC solution based on Ampleon's advanced GEN9 LDMOS technology. The device integrates the carrier and peaking devices, input splitter, and output combiner in a single package. This multi-band device is well suited for use as a general-purpose driver amplifier or small cell final stage amplifier in the 1800 MHz to 2200 MHz frequency range. Available in a PQFN package outline. Typical RF performance conditions: T_case = 25℃; I_Dq = 107 mA (carrier and peaking). Test signal: single-carrier LTE 20 MHz; PAR = 7.6 dB; measured in Ampleon f = 1990 MHz integrated Doherty application circuit.
