射频放大器 2.01-2.17GHz PAE 17% .25W Gain 30.5dB
"s is a high-linearity two-stage power amplifier in a low-cost surface-mount package with on-chip bias control and temperature compensation circuits. The amplifier provides 30.5 dB gain over the 2010 – 2170 MHz frequency range and be utilized without the need of linearization circuitry such as DPD It is able to achieve -48 dBc ACLR at +24.5 dBm output power using 20 MHz LTE signal 9.5 dB PAR. The TQP9221 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 product is bias adjustable allowing the amplifier"s power consumption to be optimized and is available in a lead-free/RoHS-compliant 7 x 7 mm surface mount package. The TQP9221 is targeted for small cell or enterprise Femtocell basestation applications, distributed antenna systems DAS, repeaters, and/or booster amplifiers.
