Overview
The 134 WLNSP QFE3320-0 device (with RR code=04) is a multimode, multiband power amplifier with

integrated low-band and mid-band antenna switches. It supports the following
ET in high power mode (HPM) for FDD systems

APT in other power mode

The 133 WLNSP QFE3320-1 device (with RR code=00) is the same silicon but it can support the following

ET in high power mode (HPM) for FDD systems

APT + DPD in high power mode (HPM) for FDD systems

APT in other power mode

The only thing different between 134 WLNSP QFE3320-0 and 133 WLNSP QFE3320-1 is that one ground

pin (89) was removed from 134 WLNSP QFE3320 package
