Description
Skyworks SKY65170-21 is a fully-matched, 0.5 W Power
Amplifier (PA) with high efficiency, designed for use in the 860 to
960 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 SKY65170-21 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
Output Compression Point (OP1dB), Adjacent Channel Leakage
Ratio (ACLR), Adjacent Channel Power Ratio (ACPR), and
efficiency when integrated in a 50 Ω system.
The primary bias to the SKY65170-21 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 SKY65170-21 is
shown in Figure 2.

Technical Description
The SKY65170-21 PA contains all of the needed RF matching and
DC biasing circuits. The device is a two-stage, HBT InGaP device
optimized for high linearity and power efficiency. These features
make the device suitable for wideband digital applications, where
PA linearity and power consumption are of critical importance
(e.g., femtocell and infrastructure applications).
The device has been characterized with a standard CDMA2000
modulated signal. Under these stringent test conditions, the
device exhibits excellent spectral purity and power efficiency.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
SKY65170-21 are provided in Table 2. Electrical specifications are
provided in Table 3.
Typical performance characteristics of the SKY65170-21 are
illustrated in Figures 3 through 7.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
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.
