By
Telecom Lead Team: Avago Technologies, a supplier of
analog interface components for communications, industrial and consumer
applications, introduced MGA-43128, a high-gain, high-linearity power amplifier
for high-data-rate applications found in 700-800 MHz cellular infrastructure equipment.
The
new MGA-43128 amplifier can serve as
a base station driver amplifier and also provides superior signal transmission
quality with low power consumption for LTE AP, CPE, and Picocell equipment.
The Avago
amplifier provides superior signal quality while transmitting at high data
rates. The MGA-43128 amplifier can reduce power consumption with low distortion
and high power added efficiency (PAE).
RF
input is fully matched while the output includes integrated pre-match circuitry
for matching and application simplicity. An integrated bypass switch controlled
attenuator provides up to 18.0 dB attenuation. The device operates over a
temperature range of -40° C to +85° C and also has a temperature-compensated
power detector on chip.
The
new MGA-43128 device’s very linear output power is achieved by using an Avago
proprietary 0.25 µm GaAs Enhancement-mode pHEMT process, which allows single 5V
supply operation and useable performance down to 3.3V.
The
700 MHz MGA-43128 joins Avago’s 29 dBm linear power amplifier family, following
the released MGA-43228 and MGA-43328 power amplifiers that cover 2300 to 2500
MHz and 2500 MHz to 2700 MHz, respectively.
The
MGA-43128 is offered in a miniature 5.0 x 5.0 x 0.85 mm surface mount, 28-lead
QFN package.
PLX Technology and Avago Technologies recently announced a
collaboration using optics to demonstrate PCI Express extending beyond its
dominant role within the box to a cabled box-to-box solution.
