Qorvo's TQP9109 is a high efficiency two-stage driver amplifier in a low-cost surface-mount package. The amplifier is able to achieve high performance with +46 dBm OIP3 and +27.5 dBm P1dB while only consuming 225 mA current. The linear amplifier integrates two high performance amplifier stages onto a module to allow for a compact system design. The input is internally matched and the amplifier only requires minimal external components for operation. The integrated interstage match minimizes performance variation that would otherwise be attributed to external matching component value and placement tolerances.
The output stage amplifier is bias adjustable allowing the amplifier's power consumption to be reduced for occasions when the high power performance is not required. The output stage can also be turned off when not being used for power savings. The output match is tunable externally to allow the amplifier to be optimized for high power or high linearity applications. Up to 46 dBm OIP3 can be achieved when optimized for linearity. The TQP9109 is available in a RoHS-compliant 20-pin 4x4mm surface mount package.
