GENERAL DESCRIPTION

The SGM33685C is a power amplifier (PA) which can

support 350MHz to 400MHz, 450MHz to 460MHz and

470MHz to 510MHz. The device uses advanced

InGaP/GaAs HBT (heterojunction bipolar transistor)

process, so it features high linearity, high efficiency and

high ruggedness.

The SGM33685C is available in a Green TQFN-3×3-16L

package.
