    The TQP9421 is a high-linearity two-stage power amplifier in a low-cost surface-mount package with on-chip bias control and temperature control circuits, suitable for small cell base station applications. The TQP9421 provides 30 dB gain and +27 dBm linear power over the 2.11 - 2.17 GHz frequency range. This amplifier is able to achieve −50 dBc ACLR at +27 dBm output power using 20 MHz LTE signal. The TQP9421 integrates two high performance amplifier stages onto a module to allow for a compact system design and requires very few external components for operation. The amplifier is bias adjustable allowing the amplifier’s power consumption to be optimized. The TQP9421 is available in a 7 x 7 mm surface mount package.
