QPA9143中文资料2.3 - 3.8 GHz 100 Ohm Differential Input Gain Block数据手册Qorvo规格书

描述 Description

The QPA9143 is a 100Ω differential input to 50Ω single ended output, wideband gain block. It is well suited as the 5G m-MIMO BTS Tx path first gain stage, to directly interface with the DAC of the transceiver, eliminating the need for a discrete balun.
With Qorvo's GaAs E-pHEMT process and SOI IPD balun, this amplifier delivers exceptional performance with 18 dB of small signal gain and 35 dBm output 3rd order intercept (OIP3). The amplifier has excellent gain flatness of 0.5 dB over any 400 MHz bandwidth and a CMRR of 35dB.
The amplifier features a shut-down function through VPD pin control. The QPA9143 is optimized over 2.3-3.8 GHz band and is housed in a compact 2X2mm SMT package.
