Product Overview
The Qorvo
®
QM77031 is a multi-mode, high efficiency linear Mid
Band and High Band S-PAD (Switched PA plus Duplexer)
module designed for use as the integrated RF front-end in multi-
mode WCDMA / CDMA / LTE mobile cellular equipment. The
high efficiency S-PAD contains three amplifier paths for 3G/4G
Mid and High Band frequencies followed by distribution
switches, filters/duplexers/quadplexer and antenna switches for
multi-band coverage of both transmit and receive functions.
QM77031 band select and bias are programmed through two
Mobile Industry Processor Interface (MIPI) buses. The
QM77031 transmit-receive module supports Average Power
Tracking (APT) for higher system efficiency at various power
levels and modulations, as well as Envelope Tracking (ET) for
current consumption optimization.
The QM77031 is packaged in a RoHS-compliant, compact
62-pin, 6.5 x 8.6 x 0.8 (max) mm surface-mount leadless
package.
