While 5G gets all the hype LTE will stay with us for years to come. Indeed, people still buy LTE phones for everyday use. Qorvo’s QPA9901 high-efficiency amplifier operates in the 3GPP Band 66 (2110 MHz to 2200 MHz) and with Band 1 small-cell wireless infrastructure systems. The major U.S. carriers all use Band 66 for LTE operation.
The QPA9901 boasts a 32% (typ) power-added efficiency at a power output of 28 dBm, as tested with a 20 MHz LTE channel. Minimum output power at the 3 dB point is 35 dBm. ACPR ranges from -33 dBc to -48dBc depending on test conditions.
