Reference Design
8 Watt mMIMO 3.4 - 3.8 GHz RF Front End Reference Board
Full RFFE Reference Design for Wireless Infrastructure 5G mMIMO Applications
Key Features
- Complete RF front end reference design from digital front end to antenna filter.
- Includes QPA9122M, QPB3810, QPB9362, directional coupler for DPD, and circulator.
- Designed for small form factor that can be integrated directly into an array.
- Instantaneous bandwidth of up to 400MHz.
- > 60dB of Tx lineup gain.
- TDD capable with Tx/Rx switching from a single control logic.
- Easy to bias. Requires only +5 and +48V.
The reference design provides a complete solution for a RF front end (RFFE) for an 8W average output power mMIMO 5G application in band n78 (3.4-3.8GHz). The RFFE reference design provides a Tx/Rx solution from digital front end to antenna filter in a compact layout which can be directly implemented into an array. For the transmit chain the reference design features the QPA9122M as a wideband high linearity pre-driver and the QPB3810 as a highly efficient GaN final stage power amplifier module. The transmit chain also includes a directional coupler for DPD observation path as well as a circulator. For the receive chain the reference design includes the low noise QPB9362 switch LNA.
Typical Applications
