Infineon – BGSA20VGL8/ BGSA20UGL8 – High RF Voltage Dual SPST Antenna Aperture Shunt Switch
The BGSA20VGL8/ BGSA20UGL8 are versatile Dual Single-Pole Single-Throw (SPST) RF antenna shunt aperture switches optimized for low COFF as well as low RON enabling applications up to 6.0 GHz. This single supply chip integrates 2 digital control pins. Unlike GaAs technology, the 0.1 dB compression point exceeds the switch maximum input power level, resulting in linear performance at all signal levels and external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally. Due to its very high RF voltage ruggedness, it is suited for switching any reactive devices such as inductors and capacitors in RF matching circuits without significant losses in quality factors
Features:
- Dual SPST designed for high-linearity antenna aperture switching and
- RF tuning applications
- > 80 V (BGSA20UG) / 67V (BGSA20VG) RF voltage OFF state handling
- Low RON resistance of 2.3 Ω (80V) / 1.6 Ω (67V) at each port in ON state
- Low COFF capacitance of 200 fF (80 V) / 240 fF (67 V) at each port in OFF state
- Low harmonic generation GPIO control interface – including 4 control states
- Supply voltage range: 1.65 to 3.6 V
- No RF parameter change within supply voltage range
- Small form factor 1.1 mm x 1.1 mm (MSL1, 260° C per
Benefits:
- Performance stability over full temperature and power supply range
- Good small and large signal RF performance up to 6GHz
Target applications:
- Suitable for EDGE/CDMA/WCDMA/C2K/LTE/5G Applications
- Impedance Tuning/Antenna Tuning/Inductance Tuning/Tunable Filters
Competitive advantage:
- With BGSA20VG/ BGSA20UG, Infineon offers the smallest 2xSPST antenna aperture shunt switches on the market
- These two products fulfil the latest Qualcomm chipset (SD865) 1.8 V nominal supply voltage rail requirement (VDD min: 1.65 V)
