BFR32-17S-A206

BFR32-17S-A206, as a family of devices, is mostly used in aerospace and telecommunication fields. It is a series of high-frequency power Doubler and multiplier from Bourns, Inc., a company specialized in fabrication low- and medium-power microwave components and subsystems. It is featured with low temperature drift, low DC insertion loss, low harmonic distortion, and low broadband noise.

This Doubler utilizes a unique design of Buffer Amplifier (pre-amplifier) and conventional Schottky diode rings for harmonic generation. And the output stage of the Doubler composes of 28dB insertable amplifier , capable to provide Low Noise Amplification also the amplification gain and output power of this doubler is adjustable. The whole design is CMOS based with active bias using for DC bias stabilization.

In details, BFR32-17S-A206 consist of many individual components such buffers, filter, mixer, multiplers power amplifier, and encoder. First, the Buffer Amplifier is used to upgrade the input voltage level and to provide a low impedance for the following amplifier stages. The next part is the Schottky diode ring, is used to generate high frequency harmonic by input signal. Then some active stages is used to filter and amplify the output frequency from Schottky diode. And a power/gains analysis subsystem is used for adjusting the output power and gain from the doubler with a precision of 0.1dB per step.

In conclusion, the BFR32-17S-A206 power doubler is an ideal choice for so many application fields, such as satellite communications, mobile communication, high-capacity data links, broadband CATV. The harmonics-rich output and low noise design ensure its ability with superior performance.
