Description
Skyworks SKY65171-21 is a fully-matched, 0.5 W Power
Amplifier (PA) with high efficiency, designed for use in the 1930 to
2170 MHz band.
The device is fabricated using Skyworks high reliability Indium
Gallium Phosphide (InGaP) Heterojunction Bipolar Transistor (HBT)
technology. This process allows for single supply operation while
maintaining high efficiency and good linearity.
The SKY65171-21 contains all of the active bias and RF matching
circuits, which make it easy to integrate into 50 Ω RF systems.
The internal input and output match are optimized for gain, 1 dB
Compression Point (P1dB), Adjacent Channel Power Ratio (ACPR),
Adjacent Channel Leakage Ratio (ACLR),and efficiency when
integrated in a 50 Ω system.
The primary bias to the SKY65171-21 can be supplied directly
from a single 5 VDC supply. The PA is designed to operate with
lower current by reducing the bias voltage.
The device is internally matched and mounted in a 20-pin,
6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology
(SMT) package, which allows for a highly manufacturable low cost
solution. The device package and pinout for the 20-pin MCM are
shown in Figure 1. A block diagram of the SKY65171-21 is shown
in Figure 2.
