Interface to RF Connector
Figure 2-11 shows a sample connection of a module’s antenna pad at the bottom layer of the module PCB with an
application PCB’s coaxial antenna connector .Line impedence depends on line width, but also on other PCB
characteristics like dielectric, height and layer gap. The sample stripline width of 0.33mm is recommended for an
application with a PCB layer stack resembling the one of the PLS62-W evaluation board shown in Figure 12.For
different layer stacks the stripline width will have to be adapted accordingly.

1）For getting the steady-going USB power supply, it is recommended that a 10uF（C406）filter capacitor and a 22pF
（C407）filter capacitor should be used.
2）For reducing the BER of USB transmission, it is recommended to add a resistor with values below 10Ω to the
DM and DP in USB interface. Just like the resistors R408 and R409 in figure 2-7.
3）For avoiding the electro-static in USB interface, it is recommended to use the ESD element. Just like the voltage

4）The USB interface input the voltage from USB_IN .For keeping the USB in U9507A module working unfailingly,
a voltage protection circuit should be added by user between the USB_IN of USB interface and the USB_VBUS PIN of
U9507A. It is shown in figure 2-8 with the red circle 2. In the voltage protection circuit, D603 is a Zener diode with a
breakdown voltage value of 5.1v which could keep the voltage on the USB_VBUS PIN of U9507A not more than
5.1v. D602 is a Schottky Diode, and R621 is a resistor with the value 1KΩ. On the other hand the voltage coming
from the USB_IN also could be converted by using a DC/DC converter to 3.6v and then be sent to VBAT PIN of
U9507A. It is shown in figure 2-8 with the red circle 1.

4.3 PHONE BOOK
4.3.1 Set Phone Book Storage Location
Phone book storage location can be set by AT command AT+CPBS. The AT command can be used in three ways.
Performing AT+CPBS? will return the current storage location of the phone book. Such as
+CPBS:<storage>[,<used>,<total>].The parameter <total> indicated how many phone numbers can be stored on the
phone. The parameter <used> indicates how many phone numbers have been stored.
Performing AT+CPBS=? will return all the storage type which the phone supports. Such as +CPBS：(list of supported
<storage>s).
We can use AT+CPBS=<storage> to set storage location. There are six types storage location. It’s follow as:
“LD” --store the recently call number which have dialed (SIM).
“MC” --store the recently call number which haven’t answered.
“RC” --store the recently call number which have been answered.
“ON” -- store the phone number of itself.
“ME” --NVRAM storage
“SM” --SIM storage
4.3.2 Read Phonebook entries
When you want to read phonebook entries, you can use AT command AT+CPBR.
Performing AT+CPBR=? will list of supported index, phone number length and text length.
Performing AT+CPBR=<index1>[,<index2>] will return the content of the phonebook entry of index1. If we use
index1 and index2 at the same time ,it will return all the entries between index1 and index2. Such as
[+CPBR:<index1>,<number>,<type><text>[[...]<CR><LF>+CPBR:<index2>,<number>,<type><text>]]
The parameter <type> include 129 and 145.145 indicate which is a international phone number. 129 indicate which is a
unknown type number.
The parameter <text> is the tag of the number.
4.3.3 Write phonebook entry
When you want to write a phonebook entry on the phone, you can use AT commande AT+CPBW.
Performing AT+CPBW=? will return list of supported index, max length of phone number, list of supported phone
number types and max length of text.
We can use the command “AT+CPBW=[<index>][,<number>[,<type>[,<text>]]]” to write number on the phone. If the
parameter <number> is NULL, the command will delete the phone number on the phone of index.
Page 31 of 33
4.3.4 Find phonebook entries
We can use AT command AT+CPBF when we want to find the entry according to the text.
Performing AT+CPBF=? will return the max length of phone number and the max length of text. Such as
+CPBF:[<nlength>],[<tlength>].
When we want to find a entry, we can give the text of the phone number ,and according to the text, we use
AT+CPBF=<findtext> to find the number we want.
4.4 AUDIO
Audio functions are only available in the U9507A module.
4.4.1 Originate Call
ATD<str>[;] Mobile originate call to dial a number. <str>: string of dialing digits, dialing digits:0～9
<;> only required to set up voice call , return to command state.
The Max length of dialing digits is 20; The prefix ”+” is not counted to the length of dialing digits.
4.4.2 Answer a incoming call
ATA using the command can answer a incoming call.
ATA responds coming call by RING. It will display the calling phone number if CLIP (Calling Line Identity Indication
Presentation) function is set. ATA will return NO CARRIER for responding hang up after connection.
4.4.3 Disconnect call
AT+CHUP using the command can disconnect a connection.
