1.0 Type1DX Introduction
Type1DX (1x1) is WiFI+BT/BLE combo SIP module with Broadcom CYW4343W, which is Single-Chip 2.4GHz WLAN
IEEE 802.11 b/g/n MAC/Baseband/Radio, Bluetooth 4.1 support chip. (See CYW4343W datasheet).
There are LPF and matching circuit in front of CYW4343W chipset. Ant port is tuned as 50 ohm output. Fast clock (X’tal)
is also embedded. Some external components will be required to complete WiFi/BT/BLE circuit. This module is covered
with resin molding and fully shielded with metal. The package type is LGA (SMD type).

5.0 HW Design Guideline
5.1 Underneath of module
Do not arrange any lines under the module to avoid deteriorations of RF performance. (all GND plane)
©2015 Murata Manufacturing Co., Ltd.
Type1DX Application note Page 8 of 13 www.murata.com
5.2 Antenna line
Antenna line should be 50ohm (*). There should be enough GND via along with Antenna line. Make sure that
pi matching circuit is located right before the wifi antenna on the main board.
(*) How to make 50ohm line?
http://www17.plala.or.jp/i-lab/index_e.htm
Here are the conditions of 50ohm lines of evaluation board. (One of example)
Epsilon : 4.3
RF trace width(s) : 0.35mm
GND gap(h) : 0.18mm
GND gap(w) : 0.5mm The line impedance is Z0 = 51.8ohm.

5.3 VBAT/CBUCK line
Make the line from SR_VLX to VIN_LDO as short as possible. 4.7uF capacitor should be as close to VIN_LDO as possible.
If the main board is multilayer PCB type, it’s better to separate the GND place for this area on the top later, then connect
it to the main GND thru the via hole on the lower layer.
On VBAT line, 4.7uF bypass capacitor should be located as close to the module as possible.

5.4 SDIO line - 1
Keep the space between SDIO_CMD line and SDIO_CLK line as much as possible to avoid coupling.
5.5 SDIO line - 2
Arrange SDIO lines with 50 ohm and put R, C parts, just in case, to reject the noise as follows if the space is allowed.
These lands can be used as test pad for the debug purpose as well.

5.6 SDIO line - 3
10 to 100k ohm pull-ups are required on the four DATA lines and the CMD line. This requirement must be met during all operating states by using external pull-up resisters or properly programming internal SDIO Host pull-ups. This module (Type1DX) does not have internal pull-ups on these lines inside module.
