SKY66002-11: 1900 to 2025 MHz, +19 dBm Linear Power
Amplifier
Applications
Residential femtocells
WCDMA, Band II
Small cells
Description
The SKY66002-11 linear Power Amplifier (PA) is a fully matched
surface mount module developed for WCDMA applications
operating from 1900 to 2025 MHz. The device meets the stringent
spectral linearity requirements of WCDMA femtocell applications
with high power-added efficiency. An integrated directional
coupler eliminates the need for any external coupler.
The
GaAs
MMIC contains all active amplifier circuitry, which
includes input and interstage matching circuits. An output match
into a 50
Ω
load, realized off-chip within the module package,
optimizes efficiency and power performance.
The SKY66002-11 is manufactured with Skyworks InGaP
GaAs
HBT process, which provides for all positive voltage DC supply
operation and maintains high efficiency and good linearity. The
primary bias to the device can be supplied directly from any
suitable power supply with an output of 4.2 V. Power down is
achieved by setting the VEN pin to 0 V. No external supply side
switch is needed since typical “off” leakage is a few microamps
with full primary voltage supplied from the main power supply.
The SKY66002-11 is packaged in a 10-pin, 3 x 3 mm Multi-Chip
Module (MCM), which allows for a highly manufacturable low-cost
solution.
The 10-pin MCM package and pinout are shown in Figure 1. A
functional block diagram of the SKY66002-11 is shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.

Technical Description
The SKY66002-11 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., small cell and infrastructure applications).
The device is designed for standard WCDMA modulated signals.
Under these stringent test conditions, the device exhibits excellent
spectral purity and power efficiency.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66002-11 are provided
in Table 2. The recommended operating conditions are specified
in Table 3 and electrical specifications are provided in Table 4.
Typical performance characteristics of the SKY66002-11 are
illustrated in Figures 3 to 9.

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.
Note 2:
Case operating temperature (Tc) refers to the temperature of the bottom ground pad.
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.
