General Description
The QPA9805 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 and decoupling caps.
The QPA9805 provides 27.4 dBm P1dB with 20 dB gain
and +43.2 dBm OIP3 across a wide frequency range of
600-1000 MHz to cover the 3GPP Bands 5, 6, 8, 12, 13, 14,
17 and 71. 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
QPA9805 is packaged in a small 5 x 5 mm leadless
package that is internally matched to 50 Ω on all RF ports.

Application Note  –  Reduced Bias Performance
The QPA9805 can be configured to be operated with lower bias current either by lowering VCC_CTRL1 or by replacing L4 with
a resistor and leaving VCC_CTRL1 = VCC. Typical performance is displayed below for various quiescent current settings.

3. Contact plating: Au over Ni
PCB Mounting Pattern
Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Use 1 oz. copper minimum for top and bottom layer metal.
3. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We recommend a 0.35mm
(#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25 mm (0.10”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
