NuWaves Introduces Bidirectional RF Power Amplifier
with Integrated Linearization Technology
-- New Product is Ideal for Half-Duplex RF Transceivers with Amplitude-Modulated Waveforms
Middletown, Ohio, July 30th, 2013 – NuWaves Engineering, an international Radio Frequency
(RF) and Embedded Systems solutions provider, announces the release of the NuPower Xtender(TM)
Linear Bidirectional S-Band Power Amplifier (PA) module, model number
NW-LBSSPA-10W-2.2-2.5, designed for use with half-duplex RF transceivers operating amplitude-modulated
waveforms (e.g. OFDM, QAM). The product is the first linearized model to come from the company’s
new Xtender series of bidirectional power amplifiers, which are based on the successful NuPower(TM)
broadband, high-efficiency, miniature PA module product line.
analog pre-distortion techniques to maximize power efficiency and reduce power back-off requirements,
the Xtender Linear Bidirectional S-Band PA generates 6 Watts of average RF output power
from 2200 to 2500 MHz, given a 10 dB Peak-to-Average Power Ratio (PAPR) waveform.
With continuous wave (CW) signals, the bidirectional PA generates a robust 10 Watts of
RF output power. To support a variety of different data links, the Xtender features automatic
transmit sensing circuitry that provides nearly instantaneous switching between receive and
transmit modes, at less than 2 microseconds, as well as manual mode switching for data links
with an available T/R signal output.
The latest NuPower Xtender bidirectional PA is both
compact and rugged. Its nickel-plated aluminum chassis occupies only 3.00” x 2.00” x 1.15” (6.9
cubic inches) and weighs less than 6 ounces, making it ideal for integration into small
platforms, such as Group 2 and Group 3 Unmanned Aircraft Systems (UAS), Unmanned Ground Vehicles
(UGV), etc. The Xtender’s optional integrated low noise amplifier (LNA) provides 8 dB of small
signal gain and lowers the maximum noise figure to 3 dB in order to improve the receive
performance of the entire communication system. Custom frequency band configurations ranging
from 500 MHz up to 4.2 GHz are possible with the Xtender design.
application of leading-edge amplifier linearization techniques is accelerating the evolution
of power-efficient bidirectional power amplifiers for modern communication systems,” said Jeff
Wells, President and CEO of NuWaves Engineering.
