BGSA149MN10

Overview

Ultra small antenna tuning SP4T with resonance stoppers

The BGSA149MN10 is a single-pole four throws (SP4T) antenna tuning switch optimized for RF applications up to 7.125GHz. It is made of 4 low ON resistance / low OFF capacitance series switches and 4 shunt to ground switches enabling on-demand open-reflective or short-reflective OFF ports behavior. This last feature is of great value to reduce antenna engineer development time in case of unwanted antenna resonance or to improve antenna efficiency with less component tuning effort.

Summary of Features

  • Low RON resistance of 1.5 Ω in ON state
  • Ultra low COFF capacitance of 80 fF in OFF state
  • RF operating voltage handling 50 V in OFF state
  • MIPI RFFE 2.1 control interface
  • Support both 1.8V and 1.2V VIO operation
  • External USID_SEL pin enabling 4 default USID addresses
  • Small form factor 0.95 mm x 1.3 mm (MSL1, 260 °C per JEDEC J-STD-020)

Potential Applications

  • Impedance, antenna and inductance tuning
  • Tunable filters
