The QPA9842 is a balanced amplifier module that oeprates from 3.4 to 3.8 GHz covering the 3GPP bands 42 and 43. It provides a P1dB of 25 dBm with a gain of more than 17.5 dB and OIP3 of 38.2 dB. The balanced amplifier configuration provides very good input and output VSWR and is especially ideal as the output stage in a macrocell transceiver board that connects to the high power amplifier (HPA) board through a long cable or microstrip trace. It has embedded hybrid couplers to convert to single ended input and output ports. The module has an enable pin to allow for shutting down of the amplifier. The module requires minimal external components which are VCC choke inductors, decoupling caps and resistors for bias control. It is available in a small 5x 5mm leadless package and is ideal for base stations, wireless infrastructure and network infrastructure applications.
