Power amplifier matching RF system and method using bulk acoustics wave device

An RF system includes a power amplifier with output impedance and a BAW filter with an input impedance and output impedance. A matching network includes an inductance connecting the power amplifier to the BAW filter and an impedance transformation ratio of at least 1:10 is provided at the output imp...

Summary:An RF system includes a power amplifier with output impedance and a BAW filter with an input impedance and output impedance. A matching network includes an inductance connecting the power amplifier to the BAW filter and an impedance transformation ratio of at least 1:10 is provided at the output impedance of the power amplifier to the output impedance of the BAW filter.
