Modular RF Front End

Multi-Band, Multi-Mode RF X2 MIMO Front End Module

The NewEdge Signal Solutions High Power Modular RF Front End Module is aimed at Multi-Band and Multi-Mode operation. The module includes the following:

  • Two Broadband Envelope Tracking (ET) RF amplifiers covering 1.8 to 2.7GHz with 7 Watts of Average RF power per PA and 55dB total gain. The PA modules include VSWR detection
  • Two Broadband Transceivers and Receive LNAs
  • Multi-Arm Core FPGA
  • Baseband processing embedded firmware for Crest Factor Reduction (CFR), Digital Pre-Distortion (DPD) and Digital Interface to support Envelope Tracking Power Amplifiers.

Each PA may be operated using envelope tracking for use with amplitude modulated waveforms such as 4G (LTE) and 3G or with constant bias voltage to support constant envelope waveforms.


The Modular RF Front End Module includes several noteworthy features, including:

  • Small size: 5.5" by 6.5"
  • High Efficiency: <55W consumed when both PA'quo;s are transmitting full power
    • Includes all baseband processing (CFR & DPD)
  • Multi-Mode: Power supply may be configured for ET or Constant Voltage operation
  • High RF Power: 44 Watts Peak / 7W Average* Per PA * 7.5dB PAPR assumed
  • Frequency Domain Duplex (FDD) and Time Domain Duplex (TDD) LTE supported
    • Individual TDD controls for each RF channel
    • Low noise power amplifier shutdown using GaN Gate pinch-off
    • Transmit off time >17µs (IAW 3GPP specification)
    • Onboard controls available for optimum T/R Switch control timing
  • Broad RF Bandwidth: Tx = 1.8 to 2.7GHz Rx = 1.7 to 2.7GHz
  • Independent Mode control for each channel
  • Complete PA: All gain stages, power sequencing and supplies included
  • LNA Specs: Input P1dB = 1.5dBm and Noise Figure < 1dB
  • Peripheral equipment control interface (+3.3V logic) incorporated
  • 3GPP (LTE) ACLR1 Better than -48dBc ACLR1 for LTE 10MHz
  • PA Modules pluggable into RF Carrier board. Modules with different powers and frequencies can be easily swapped in.
  • Broadband transceivers and VSWR detection included
  • Ethernet and USB interfaces
