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.
