RFMW announced a new high linearity two-stage power amplifier designed for distributed amplifier systems (DAS), small cell infrastructure and repeaters.
The TQP9421 provides 30 dB gain and +27.5 dBm linear power over the 2.11 – 2.17 GHz frequency range. This amplifier is able to achieve -48 dBc ACLR at +27.5 dBm output power using 20 MHz LTE signal without the need for external linearization, claims the company.
Drawing 450mA from a 4.5V supply, the device is packaged in a low-cost 14-pin, 7x7mm, lead-free/RoHS-compliant DFN package with a large backside paddle to aid in heat dissipation.
The device features on-chip bias control and temperature control circuits. It also 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.
