Qorvo offers the QPA9154 wideband gain block with a 50 Ω single-ended input to 100 Ω differential output. It is ideally suited as the 5G m-MIMO BTS Rx path final gain stage, to directly interface with the ADC of the transceiver, eliminating the need for a discrete balun.
Features for the QPA9154 include 19 dB of small signal gain, 35 dBm output 3rd order intercept (OIP3), and an excellent gain flatness of 0/5 dB over any 400 MHz bandwidth. The amplifier features a shut-down function through VPD pin control. It is optimized over 2.3 – 3.8 GHz band and is housed in a compact 2 x 2 mm SMT package.
