Description
The SKY65146 is a fully matched 28-pin surface mount multi-chip
module (MCM) amplifier designed for Private Mobile Radio,
Wireless Local Loop, and TDMA/AMPS mobile units operating in
the 806-849 MHz cellular bandwidth. Microwave Monolithic
Integrated Circuits (MMICs), comprised of Gallium Arsenide (GaAs)
and Si CMOS, contain all active circuitry in the module, which
includes on-board bias circuitry as well as the interstage
matching circuit. The input and output match is realized off-chip
within the module package to optimize efficiency and high power
performance (P3 dB_sat
≅
35.6 dBm) into a 50
Ω
load.
Primary bias to the SKY65146 can be supplied directly from a
single cell lithiumion or other suitable battery with a nominal
output of 3.5 V.
No external supply side switch is needed as typical “off” leakage
is a few microamperes with full primary voltage supplied from
the battery.

The ICs are manufactured on an advanced InGaP HBT process and
on a silicon CMOS process, providing for all positive voltage DC
supply operation while maintaining high efficiency and good linearity.
The module can operate over the temperature range of -40 ˚C to
85 ˚C. A populated evaluation board is available upon request.

Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

CAUTION:
Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
1. For pulsed operation with duty cycle < 25%.
2. When amplifier is biased off (V
REG
= 0 V).
3. Voltage on V
REG
pin may not exceed the applied V
CC
voltage.
Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty. Each absolute maximum rating listed is an
individual parameter. Biasing and driving the amplifier with more than one absolute maximum
rating listed may result in permanent damage to the device. Exposure to maximum rating
conditions for extended periods may reduce device reliability.
