MC13853 LNA Evaluation Board User’s Guide, Rev. 1.3
Freescale Semiconductor v
About This Book
This user’s guide provides a detailed description of the hardware of the MC13853 evaluation board demo
kit. It documents the RF, DC, and control requirements for proper operation in three bands (GSM850,
PCS1900, and WCDMA 2100).
The objective of this manual is to establish guidelines to facilitate the use of this LNA on a PCB evaluation
board, namely:
• The RF interface, input and output.
• The DC supplies and logic control inputs.
• The serial peripheral interface (SPI).
Audience
This manual is intended for the end-user of the MC13853 evaluation board.
Organization
This document is organized into three chapters and one appendix:
Chapter 1: Initial Instructions
Chapter 2: Evaluation Board
Chapter 3: Test Equipment Bench Line-up
Appendix: DC and Control Wiring Harness
Revision History
The following table summarizes revisions to this document since the previous release (Rev. 1.2).
Conventions
Please note the following:
• All RF interconnections are to be with low loss coaxial cabling using clean SMA type RF
connectors, including using the correct manufacturer’s torque at the connecting point.
• All DC supply lines must be able to safely carry peak currents in excess of 2 A under minimum
voltage drop.
• All control lines (SPI lines and parallel cable) must be kept away from strong RF fields.
