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, 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 ohm on all RF ports.
Typical Applications
- Wireless Infrastructure
- Macro BTS Transceivers
- Booster Amps, Repeaters
