Infineon - BGSA20VGL8/ BGSA20UGL8 - High RF Voltage Dual SPST Antenna Aperture Shunt Switch

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)
