• Manufacturer Part Number: sky65146-21
• Description: Sky65146-21 806-849 Mhz, 3.5 V Broadband Power Amplifier
• Manufacturer: Skyworks Solutions, Inc.

Functional Description
The SKY65146-21 is a fully-matched, three-stage, GaAs HBT PA
with on-chip interstage matching and bias circuitry. The
input/output match is realized off-chip, but within the module
package. The PA uses series feedback on the first and second
stages to provide for high gain, stability, and power of up to 4 W.
The module includes a silicon CMOS controller circuit to provide a
regulated bias enable control for on/off operation (VREG, pin 8). In
off mode, supply current is a few microamperes with VREG = 0 V.
The module operates with all positive DC voltages while
maintaining high efficiency and good linearity. The nominal

must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
