HS8727-91 is a high-power RF switch IC for the automotive communication applications, Designed for broadband application from 0.1 to 6 GHz, this silicon-on-insulator (SOI) based single-pole double-throw (SPDT) switch IC can meet the stringent automotive requirements for various radio access technologies, such as 2G/3G/4G/5G/V2X. It can be widely used in TBOX (Telematics Box), connectivity modules, NAD (Network Access Device), OBU (On Board Unit), RSU (Road Side Unit) and other RF applications. HS8727-91 is available in a 6-pin DFN package with dimension of 1.1mm x 0.7mm x 0.38mm. Below are the major technical features of HS8727-91:

•       Advanced SOI technology provides low insertion loss and high isolation. Low insertion loss can effectively improve the RF performance of the communication terminal, while high isolation can reduce interference between channels and improve communication quality.

•       Wide operating temperature range of -40°C to 105°C, ensuring reliable performance over a stringent vehicle environment. 

•       Fast switching speed with less than 1µs on/off switching time.

•       HBM ESD protection up to 2KV, reducing the risk of electrostatic damage.

•       Suitable for both radio transmission and reception applications. Maximum power is 37dBm.

•       Compatible to all automotive platforms, including but not limited to Qualcomm MDM9x07, SA415, SA522 and MediaTek MTK2735, etc.

•       Excellent quality and reliability. In order to ensure quality and reliability for automotive applications, OnMicro has introduced a robust system to cover the entire AEC-Q100 product development and manufacturing cycle. The fact that HS8727-91 has been certified with AEC-Q100, is a proof of OnMicro's product development system.

With successful experience in obtaining AEC-Q100 certification for HS8727-91, OnMicro will increase its effort in developing RFFE products for automotive applications. Multiple products are currently under AEC-Q100 qualification tests, including RF switches, LNAs (Low Noise Amplifier), PAs (Power Amplifier), and PA modules. OnMicro is expected to offer a complete AEC-Q100 certified RFFE solutions in the near future. Stay tuned for more innovative products from OnMicro!
