High RF voltage dual SPST antenna aperture shunt switch
The BGSA20UGL8 is a versatile Dual Single-Pole Single-Throw (SPST) RF antenna shunt aperture switch 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.
Summary of Features
Dual SPST designed for high-linearity antenna aperture switching and RF tuning applications
Low RON resistance of 2.3 Ω at each port in ON state
Low COFF capacitance of 200 fF at each port in OFF state
> 80 V RF voltage OFF state handling
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 JEDEC J-STD-020)
Suitable for EDGE/CDMA/WCDMA/C2K/
LTE/5G Applications
RoHS and WEEE compliant package
Potential Applications
Impedance tuning
Antenna tuning
Inductance tuning
Tunable filters
