QPA9124 3.0 5.0 GHz 100 Differential Output Gain Block Product Overview The QPA9124 is a 50 single-ended input to 100 differential output, wideband gain block. It is well 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. 12-pin, 2x2mm SMT Package This amplifier delivers exceptional performance with rd 20.5dB of small signal gain and 34.5 dBm output 3 order intercept (OIP3). The amplifier has excellent gain flatness Key Features of 0.5 dB over any 400 MHz bandwidth and a CMRR of 3.05.0 GHz Operational Frequency 35dB. The amplifier features a shut-down function through V pin control. PD 100 Ohm Differential Output 50 Ohm Single-Ended Input The QPA9124 is optimized over 3.0-5.0GHz band and is +34.5 dBm OIP3 housed in a compact 2X2mm SMT package 20.5dB Gain Small 2x2mm SMT Package Functional Block Diagram Applications 5G m-MIMO Mobile Infrastructure General Purpose Wireless TDD / FDD System Ordering Information Part No. Description QPA9124TR7 2500 pcs on 7 reel (standard) QPA9124EVB-01 Differential Output Evaluation Board Top View Datasheet, Rev.
