The RF Switch Click Board™ features MASWSS0115, a GaAs PHEMT MMIC single-pole, double-throw (SPDT) switch in a low cost, lead-free SC-70 (SOT-363) surface mount plastic package. The MASWSS0115 is ideally suited for applications where a very small size and low cost are required. Typical applications are dual-band systems that require switching between small signal components such as filter banks, single-band LNAs, converters, etc. This part can be used for low power, low loss requirements in all systems operating up to 3 GHz, including PCS, GSM, DCS, Bluetooth, and other receive chain applications. The MASWSS0115 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.
Featured chip MASWSS0115 provides signal switching of 50MHz to up to 3GHz with an insertion loss of 0.3 dB at 2.4 GHz and power consumption of 5 µA at +2.3V. Ultra High-Speed CMOS inverter labelled as NC7WZ14 is used for driving and controlling an RF switch with the typical switching time of 3,2 ns. Additionally, a load switch TPS22943DCKR can enable or disable the RF switch by electrically detaching the power supply. RF Switch Click Board™ uses the 5V to supply the switch driver while 3.3V microcontroller can be used to communicate with the control circuitry.
Two LEDs (RF1 and RF2) indicate the current active RF port as a visual representation of a state of the switch. Since RF1 is complementary to RF2, the switching can be achieved with only one GPIO pin. The RFC is an input of the switch with the possibility of redirecting the RF signal to RF1 or RF2 port. Besides switching SEL pin, the pin labelled as ON is used for power control. All of the switch ports are accessible on the connectors located on top of the Click Board™ with the addition of miniature coaxial connectors for both RF ports.

void application_task ( )
{
mikrobus_logWrite( " Switch to RF Port 1 ", _LOG_LINE );
mikrobus_logWrite( "-----------------------", _LOG_LINE );
rfswitch_select_channel( RFSWITCH_SELECT_CHANNEL_1 );

}
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
The RF Switch Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
