BGSA200ML9

Overview

Ultra-small 2xSPST antenna tuning switch

The BGSA200ML9 is a versatile shunt to ground 2 x Single-Pole Single-Throw (2xSPST) RF antenna tuning switch. It is optimized for low COFF as well as low RON enabling applications up to 8.25GHz; ideally fitting for antenna tuning purpose.

The BGSA200ML9 integrates on-chip CMOS logic and power supply regulation. Thanks to its 4 states USID1 and USID2 feature, it can be controlled either with GPIO lines or MIPI RFFE bus. Each switch throw can be programmed individually or altogether. Up to 3 instantiations of the same device can be controlled using the same RFFE bus when in MIPI RFFE mode.

Summary of Features

  • Low RON resistance of 1.35 Ω at each port in ON state
  • Low COFF capacitance of 156 fF at each port in OFF state
  • High RF operating peak voltage handling of 48 V in OFF state
  • Low harmonic generation
  • MIPI RFFE 2.1 control interface
  • MIPI and GPIO control modes
  • 1.2V and 1.8V VIO operation
  • Extremely low current consumption of 22 µA
  • Switching speed <5 µs
  • Self-resonant frequency >8250 MHz
  • Small form factor 1.1 mm x 1.1 mm (MSL1, 260 °C per JEDEC J-STD-020) 

Benefits

  • Supporting sub-7.2GHz NR / NR-U (5G) applications
  • Ultra low RON x COFF FOM along with very high linearity
  • Usable on platforms with 1.2V supply voltage
