SGM72204A

SP4T Antenna Tuning Switch

GENERAL DESCRIPTION

FEATURES

The SGM72204A is a single-pole/four-throw (SP4T)

antenna tuning switch. The device features low

on-resistance and turn-off capacitance, high linearity,

low insertion loss and high RF voltage handling

capability, which has a very significant improvement

effect on TRP and TIS.

● Frequency Range: 0.1GHz to 2.7GHz

● Low On-Resistance: 1.0Ω (TYP)

● Low Turn-Off Capacitance: 130fF (TYP)

● Peak-Voltage Handling: 45V (TYP)

● RF Input Power: 43dBm

● Supply Range: 2.4V to 4.5V

● No External DC Blocking Capacitors Required

● Available in a Green UTQFN-1.1×1.5-10L Package

The SGM72204A is a GPIO interface product based on

SOI process, allowing customers to flexibly use its

control interface to improve product performance.

BLOCK DIAGRAM

No external DC blocking capacitors required on the RF

paths as long as no external DC voltage is applied,

which can save PCB area and cost.

The SGM72204A is available in a Green UTQFN-1.1×

Supply and Logic

1.5-10L package.
