The PAN9028 is a dual-band 2.4 GHz and 5 GHz Wi-Fi® and Bluetooth® radio module from Panasonic Industry which simplifies the integration of short-range wireless connectivity into end-product designs.
Based on the 88W8987 system-on-chip from NXP Semiconductors, the module can switch between the certified on-board chip antenna and the bottom pad, to connect to an external antenna, via a single pole double throw (SPDT) switch.
The external antenna option makes the PAN9028 suitable for use in enclosures which greatly attenuate radio signals. To meet regulatory requirements and speed up certification, the PCB tracing from the bottom pad to the u.FL antenna connector should match the Panasonic reference design.
The PAN9028 module supports 802.11a/b/g/n/ac Wi-Fi standards and the basic rate, enhanced rate and low energy forms of the Bluetooth specification. The two radio standards can operate simultaneously and independently, which enables high-speed data transfer over an 802.11ac interface while supporting low-power operation via a Bluetooth Low Energy link.
An optional integrated power management IC (PMIC) manages the four different voltage levels which the device requires. The module which includes a PMIC only needs a single-voltage supply, simplifying the hardware design.
Tables listing the allowed maximum power output on each channel are stored in one-time programmable memory. This means that Panasonic can guarantee operational approval for use in the US according to FCC regulations, in Canada according to the ISED specifications, and in Europe according to CE RED with only one part number.
The PAN9028 ENWF9408A1EF has an integrated PMIC; the PAN9028 ENWF9408A2EF has no PMIC.
Part Number: ENWF9408AVEF
The ENWF9408AVEF is a microSD adapter which includes the PAN9028 module with a PMIC, a MicroSD host interface, a UART interface and a u.FL antenna connector.
