Initial Instructions
1.1 Overview
This chapter describes the RF and control basic requirements of the MC13853 LNA evaluation board (Iota
VI).
The following items are supplied with the Freescale MC13853 Demo Kit:
1. MC13853 LNA evaluation board (Iota)
2. Serial peripheral interface (SPI) board (MMM6038SPI)
3. Control software CD-ROM
4. DC and control cable harness
The evaluation board interconnects with the MMM6038SPI via a eight wire cable. The MMM6038SPI
connects via a parallel port cable to the PC computer.
On the evaluation board, all the coaxial RF connectors are of the SMA type. In order to minimize damage
to these, connections are to be made using low loss flexible coaxial cables with male SMA connectors
mating towards the evaluation board. The mating surfaces must be clean (tissue paper and standard grade
isopropyl alcohol can be used); if not, the amplifier performance can be affected. The applied torque via a
5/16” wrench at the connecting point must not exceed the manufacturers specification. There are a total of
6 SMA female connectors attached to the evaluation board. The DC and control connector is of a 8-pin,
right-angle header type. The
Appendix A, “DC and Control Wiring Harness ” provides the details and cable
harness wiring.
Before any RF or DC cabling is attached, caution must be used that the board is grounded first. This
prevents ESD when attaching the remaining cables.
NOTE
Do not exceed the maximum ratings as given in the MC13853 Data Sheet,
in particular the maximum applied DC voltage and RF input level. Operate
in a safe ESD environment on the test bench.
Refer to Figure 1-1 . Attach the DC and control cable harness (detailed in Appendix A, “DC and Control
Wiring Harness ”) to the evaluation board:
Attach the cable harness end labeled SPI into the interface board as shown in Figure 1-1 .
