3400 – 3800 MHz 1/4W Balanced Amplifier
General Description
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
3400-3800 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 Ω on all RF ports.
