Note Section 8 and 9 are for internal use only. They are for ATE configuration.
8 Main Hub TDD Requirements:
TDD Duplex port or Simplex ports will be configured in manufacturing based on
customer requirements.
8.1 MH TDD threshold configuration:
Main Hub threshold is configured at ATE. Each band and each Sub Band have different threshold and
memory location.
MH will switch to Downlink at input power of -10dBm. This is configured at ATE with 0dB System gain.
After setting MH gain and calibration threshold, ATE will inject -10dBm signal into MH and measure
detector threshold through A/D and program it into assigned memory location. ATE will measure and
program this value into each sub band it tests.
These steps are repeated for both bands.
9 RAU TDD Threshold Requirements:
9.1 RAU Threshold Configuration
RAU Threshold is set after RAU configuration is done. Each band have different threshold, and each sub
band has different threshold.
Band 1 setup: RAU Output power is set to -10dBm and Band 1 Downlink Burst Detector output is
measured through A/D and programmed in assigned memory location. Firmware uses this location for
Comparator threshold. These steps are repeated for Band 2.
10 RAU and MH Unit
RAU need to be configured to calibrated Pout of 5dBm from RAU.
MH need to be configured to +5dBm input Power with 0dB system gain.
