CN-0150
Circuit Note
Rev. C | Page 4 of 5
If an external voltage reference is to be used, the ADR421 2.5 V
reference is recommended. Its 1 ppm/°C temperature drift results
in a reference voltage variation of only 312 μV from −40°C to
+85°C. This has a negligible effect on the overall temperature
stability of the system.
If a less dynamic range is required, the AD8317 (55 dB) or AD8319
(45 dB) log detector can be used. If a true rms responding power
measurement is required, the AD8363 (50 dB) or ADL5902
(65 dB) can be used.
CIRCUIT EVALUATION AND TEST
This circuit uses the EVAL-CN0150A-SDPZ circuit board and
the EVAL-SDP-CB1Z System Demonstration Platform (SDP)
evaluation board. The two boards have 120-pin mating connectors,
allowing for the quick setup and evaluation of the circuit’s
performance. The EVAL-CN0150A-SDPZ board contains the
circuit to be evaluated, as described in this note, and the SDP
evaluation board is used with the CN0150A evaluation software to
capture the data from the EVAL-CN0150A-SDPZ circuit board.
Equipment Needed
• PC with a USB port and Windows® XP or Windows Vista®
(32-bit), or Windows 7 (32-bit)
• EVAL-CN0150A-SDPZ Circuit Evaluation Board
• EVAL-SDP-CB1Z SDP Evaluation Board
• CN0150A Evaluation Software
• Power supply: 6 V or 6 V wall wart
• Environmental chamber
• RF signal source
• Coaxial RF cable with SMA connectors
Getting Started
Load the evaluation software by placing the CN0150A evaluation
software CD in the CD drive of the PC. Using My Computer,
locate the drive that contains the evaluation software CD and
open the readme file. Follow the instructions contained in the
readme file for installing and using the evaluation software.
Functional Block Diagram
See Figure 1 of this circuit note for the circuit block diagram
and the EVAL-CN150A-SDPZ-SCH-Rev0.pdf file for the
circuit schematics. This file is contained in the CN0150
Design Support Package.
Setup
Connect the 120-pin connector on the EVAL-CN0150A-SDPZ
circuit board to the CON A connector on the EVAL-SDP-CB1Z
evaluation (SDP) board. Use nylon hardware to firmly secure
the two boards, using the holes provided at the ends of the 120-pin
connectors. Using an appropriate RF cable, connect the RF signal
source to the EVAL-CN0150A-SDPZ board via the SMA RF
input connector. With power to the supply off, connect a 6 V power
supply to the +6V and GND pins on the board. If available, a
6 V wall wart can be connected to the barrel connector on the
board and used in place of the 6 V power supply. Connect the USB
cable supplied with the SDP board to the USB port on the PC.
Note: Do not connect the USB cable to the mini USB connector
on the SDP board at this time.
Test
Apply power to the 6 V supply (or wall wart) connected to
EVAL-CN0150A-SDPZ circuit board. Launch the evaluation
software and connect the USB cable from the PC to the USB
mini connector on the SDP board.
Once USB communications are established, the SDP board can
now be used to send, receive, and capture serial data from the
EVAL-CN0150A-SDPZ board.
The data in this circuit note were generated using a Rohde &
Schwarz SMT-03 RF signal source and an Agilent E3631A power
supply. The signal source was set to the frequencies indicated in
the graphs, and the input power was stepped and data recorded
in 1 dB increments.
Temperature testing was performed using a Test Equity Model 107
environmental chamber. The EVAL-CN0150A-SDPZ evaluation
board was placed in the chamber via a slot in the test chamber
door, with the SDP evaluation board extending outside.
Information and details regarding how to use the evaluation
software for data capture can be found in the CN0150A
evaluation software readme file.
Information regarding the SDP board can be found in the SDP
User Guide.
