QPA9842

    2700 - 3800 MHz 1/4W Balanced Amplifier

    Key Features

    • 2700 – 3800 MHz
    • Balanced amplifier with integrated 3 dB hybrids
    • Internally Matched 50 Ohm Input / Output
    • Shutdown Mode with 1.8V Logic Control
    • 19.5 dB Gain
    • +40.3 dBm OIP3
    • +25.0 dBm P1dB
    • Good gain flatness across Bands 42, 43

    The QPA9842 is a balanced amplifier module with embedded hybrid couplers to convert to single ended input and output ports. The module has an enable pin to allow for shutting down of the amplifier. The module requires minimal external components which are VCC choke inductors, decoupling caps and resistors for bias control.

    The QPA9842 provides 25 dBm P1dB with 19.5 dB gain and +40.3 dBm OIP3 across a wide frequency range of 2700-3800 MHz to cover the 3GPP Bands 42 and 43. The linear driver amplifier is targeted for use in wireless infrastructure where high linearity, medium power and high integration is required. The balanced amplifier configuration provides very good input and output VSWR and is especially ideal as the output stage in a macrocell transceiver board that connects to the high power amplifier (HPA) board through a long cable or microstrip trace. The QPA9842 is packaged in a small 5 x 5 mm leadless package that is internally matched to 50 ohm on all RF ports.
